“…The magnetic moment of the complex is calculated from the molar magnetic susceptibility data which were collected by the measurement for the two separated preparation (Sample 1 and 2) was found to be 6.17 and 5.87 BM at 298 K, respectively (Table 3), being normal paramagnetic nature. This reflects the spin-only value (μ s ), corresponding to five unpaired electrons in the metal ion, and it is the normal value in an octahedral geometry, as observed in some literature to be 5.89-6.16 BM for various compounds [1,9,[21][22][23]. Much lower values of several Mn(II) complexes, however, have been reported to be only 4.24 to 4.34 BM at 77-303 K [24], 4.65 BM [25], and 5.12 BM [26].…”

“…The chemistry of six coordinated bidentate, phenanthroline (phen), and bipyridine (bipy), of divalent metals such as Mn(II), Co(II), Ni(II), and Cu(II) with various counterpart anions have been much well studied concerning P-XRD [1][2][3][4][5][6][7]. Among the divalent metal complexes, not many detailed physical properties are previously reported, and Mn(II) might exhibit an important role in the development of metal-based drugs.…”

The synthesis of the complex containing manganese(II), bipyridine (bipy) as a ligand, and an anionic trifluoromethane sulfonate (triflate) is reported. The corresponding metal content, conductance, and DTG-TGA of the complex lead to the formula of [Mn(bipy)3](triflate)2·5.5H2O. The fully high-spin magnetic moment is observed, corresponding to five unpaired electrons in the metal ion. The electronic spectral bands suggest the three possible spin-forbidden transitions of the sextet to quartet states. The mode of vibrations of the IR spectrum supports the typical ring of bipy, and the triflate. The images of SEM-EDX indicate the presence of the corresponding elemental content and reflect the relatively high crystallinity, as it is evidenced in the profile of the corresponding powdered diffractogram. The refinement of powdered XRD following the Le Bail program suggests being structurally triclinic symmetry of P21/c. This complex shows inhibition of bacterial activity against S. aureus and E. coli.

“…However, it has been applied to that of iron(II) complex [28] quite recently and found to be a significant result. Since then, referring to the suggestion by Toby as well [29], application of this method has been extensively performed to some powdered complexes [30][31][32][33][34][35][36][37][38] and the results were found to be reasonably acceptable.…”

Salt of [Cu(bptrzH)Cl2], (bptrzH = 3,5-bis(pyridin-2-yl)-H-1,2,4-triazole) has been prepared and characterized its electronic spectral and magnetic properties. This salt is paramagnetic with magnetic moment, μs, being 1.77–1.78 BM at 293 K, but decreased significantly with decreasing temperature to be 0.60–0.63 BM at 90 K, indicating antiferromagnetic nature. This is associated with Cu–Cu magnetic interactions at low temperatures, and suggests that the salt adopt an octahedrally polymeric structure. The electronic spectrum of this salt reveals a strong ligand field band centered at about 13,000 cm–1 and a very strong charge transfer absorption at about 23,000–24,000 cm–1. The spectrum is better resolved at lower temperature and this is parallel to the slight change in color from yellowish-green at room temperature to bright green at low temperature (90 K). The powder XRD of this complex was refined by Le Bail method of Rietica program and found to be fit as triclinic symmetry of space group PĪ with the figure of merit: Rp = 5.02; Rwp = 7.95; Rexp = 5.40; Bragg R-Factor = 0.05; and GOF = 2.166.

“…The observed data (+ signs, (a)) are almost coincident to the full line of refinement model (b), and it is confirmed by the almost flat curve (c) reflecting difference between the two. This suggests that the analysis is considered to be fit with low figures of merit: 3.62 (Rp), 5.76 (Rwp), 3.48 (Rexp), 2.745 (GOF), and 0.05 (Bragg R-Factor) as discussed by Toby [44] and found in several of so many reported metal oxides [2][3][4] and several complexes [5][6][7][8][9]. The detailed lattice parameters of this complex are described in Table 4 along with the corresponding cationic single crystal data of different counter anions, the hexamolybdate [39], the perchlorate [40], the bis(2thiobarbiturate)-Htba [41], the chloride [42], and the tetrachloridozincate [43].…”

“…The first complex refined by Le Bail program was initially reported in 1999 [5] for octahedral [Co(NH3)5CO3](NO3)•H2O complex which was found very good result with the figures of merit to be RB = 0.053, Rp = 0.100, Rwp = 0.119. Although the application to other complexes were not continually reported since then it has been applied to some complexes as reported quite recently by Sugiyarto et al [6], Kusumawardani et al [7][8] and Sutrisno et al [9]. Therefore, refining diffractogram of powder complexes seems to be an alternative way to identify the corresponding lattice parameters.…”

The complex containing Ni(II)-2,2’-bipyridin (bipy)-trifluoroacetate (TFA) was prepared by direct interaction of the corresponding precursors in an aqueous solution. AAS measurement for metal content, TGA-DTA analysis and electrical conductance suggest the ionic complex of [Ni(bipy)3](CF3COO)2·6H2O. The magnetic moment of 3.13–3.17 BM indicates the paramagnetism corresponding to two unpaired electrons which is clearly higher than that of the spin only value (2.87 BM), and commonly observed due to the spin-orbit coupling in Ni(II). UV-Vis spectral property revealed the first two main ligand field bands centered at about 14200 and 18650 cm–1, which are attributed to the spin-allowed transition, 3A2g→3T2g and 3A2g→3T1g(F), respectively. The expected third band at higher energy seems to appear as a shoulder at 26500 cm–1 (378 nm), as it is masked by a strong intensity of charge transfer band centered at 31050 cm–1. The infrared spectrum exhibits mode of vibrations of the functional groups of ligand and TFA. The powder diffractogram was refined by Le Bail method and found fit as monoclinic system of space group of P21/M, with figures of merit: Rp = 3.62, Rwp = 5.76, Rexp = 3.48, goodness of fitting (GOF) 2.745 and the derived Bragg R-Factor = 0.05.
