“…The ―NCH 2 and ―OCH 2 protons of the morpholine ring show a triplet at δ 4.01–4.10 and δ 3.69–3.75, respectively . Complexes 4 and 5 exhibit a singlet at δ 9.78 and δ 10.34 due to ―OH proton.…”

“…It has been observed that the complexes are found to have crystalline structures, nano‐range particle size (16.32–19.97 nm), lower symmetry (monoclinic) with unit cell volume V = 4823.35 × 10 −8 cm –3 ( 1 ), V = 5684.23 × 10 −8 cm –3 ( 4 ) and V = 4825.79 × 10 −8 cm −3 ( 6 ). The Debye–Scherrer formula was used to determine the average crystallite size using full width at half‐maximum (FWHM) of the diffraction peaks:

D = \frac{italicKλ}{B cos θ}

where D = particle size, K = is a constant (value = ~0.9), λ = wavelength, B = FWHM and θ = Bragg angle.…”

Some mixed bis(morpholine-4-dithiocarbamato-S,S′)antimony(III) complexes [(OC 4 H 8 NCS 2 ) 2 SbL] with oxygen or sulfur donor ligands [L = -OOCCH 3 (1), -OOCC 6 H 5 (2), -SOCCH 3 (3), -SCH 2 COOH (4), -OOCC 6 H 4 (OH) (5), -SCH 2 CH 2 CH 3 (6), -OC 6 H 5 (7), ½ -SCH 2 CH 2 S-(8)] have been synthesized by reacting the chloro-bis(morpholine-4-dithiocarbamato-S,S′)antimony(III) with corresponding oxygen or sulfur donor ligands in 1:1 or 2:1 stoichiometries. These have been characterized by melting point, molecular weight determination (cryoscopically), antimony (iodometrically) and sulfur (gravimetrically) estimation, elemental analyses (C, H and N), UV-visible, FT-IR, far IR, multinuclear NMR ( 1 H and 13 C)], TG/DTA analysis, ESI-mass and powder X-ray diffraction studies. The splitting of the strong band observed at 1046-1066 cm À1 due to υ(C-S) indicated anisobidentate mode of binding of the dithiocarbamate group, which was further supported by a 13 C NMR signal appearing at around δ 200 due to NCS 2 moiety. The base peak observed at m/z 444.9 supports the strong chelating nature of the morpholine-4-dithiocarbamate compared to the other hetero ligands used. TGA revealed that, complexes 21 and 4 were decomposed in three steps; also 6 was decomposed in two steps, followed by the formation of Sb 2 S 3 . The results obtained by antimicrobial screening tests indicate that complex 3 showed a maximum zone of inhibition (20 mm) against Trichoderma ressie at a concentration of 200 μg ml À1 . Complexes 2, 3 and 8 are most active (zone of inhibition (ZI) 17-20 mm) against both of the fungal species Aspergillus niger and Trichoderma ressie as well as complex 4 (ZI 17 mm) and 6 (ZI 18 mm) against Trichoderma ressie.

In the present study, Diethyl 4-amino-1-(3-chlorophenyl) -1H-pyrazole-3,5 dicarboxylate (D4A1(3-cl)1HP35D) was synthesized. The structure of newly synthesized compounds of Diethyl 4-amino-1-(3-chlorophenyl -1H-pyrazole-3,5 dicarboxylate was characterized by x-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR) and Transmission electron microscopy (TEM). The compound has been prepared by the chemical root method and crystal structure was determined by x-ray diffraction technique. The XRD pattern of (D4A1(3-cl)1HP35D) confirms the crystalline nature and (h k l) values are indexed. From the experimental analysis, the presence of functional groups in the synthesized compound and particle size of the compound has been estimated by FTIR and TEM spectroscopy.

“…Thermal decomposition of the cooper (II) complex is accompanied by its melting and with an exothermic structural rearrangement [11]. During the last two years, these thermal techniques have been used to study the stability and to characterize the degradation process of several dithiocarbamate complexes [12][13][14]. On the other hand, a study of the degradation process for three novel selenocyanato complexes has been published recently [15].…”

“…Besides, antimony metal containing compounds are commonly used to treat parasitic infections and exhibit a broad spectrum of chemotherapeutic applications and cytotoxic activities. So, a study has reported the synthesis, spectroscopic, thermal and structural behavior of antimony(III) bis(pyrrolidinedithiocarbamato)alkyldithiocarbonates [12]. Thermogravimetric studies not only allows to determine purity and thermal stability of the complex but also composition of the complex as well which it is observed during different steps of weight losses as a fragment formed in different temperature ranges [12].…”
