“…This value of μeff(T) at 300 K was slightly higher than the expected spin-only value of 1.73 μB/Cu and was attributed to a small effective g value, i.e., geff = 2.26 (μeff = geff[S(S + 1)] 1/2 , S = total-spin angular momentum quantum number). Below 15 K, μeff(T) decreased, reaching 1.91 μB/Cu at 5 K, which could be attributed to the intermolecular interactions between the Cu(II) ions [56,57]. In the 2D framework of 2, the inter Cu distances through the 4, 4′-bipyridylamine…”

A one-dimensional (1D) coordination polymer [Cu2(bpba)(CH3COO)4] (1) and a two-dimensional (2D) coordination polymer [Cu(bpba)2(H2O)(NO3)](NO3)∙2H2O∙MeOH (2) were synthesized by the reaction between Cu(CH3COO)2∙H2O/Cu(NO3)2∙3H2O and bis(4-pyridyl)benzylamine (bpba). The Cu(II) ions of 1 and 2 have distorted-square pyramidal coordination with a paddle-wheel structure and an octahedral geometry, respectively. By coordinating the Cu(II) ions and bpba ligands, 1 and 2 formed zigzag 1D and puckered 2D coordination polymers, respectively. Polymer 1 exhibits strong emissions at 355 and 466 nm, whereas polymer 2 exhibits strong emissions only at 464 nm. The emissions are strongly dependent on the geometry of the Cu(II) ions linked by the bpba and anionic ligands. Polymer 1 exhibits a very strong antiferromagnetic interaction within the paddle-wheel dimer, whereas polymer 2 exhibits a very weak antiferromagnetic interaction through the bpba linkers and/or space.

“…These spectra show two bands for the CN stretching mode, with a frequency difference of about 20 cm -1 . [20] The IR spectrum also provides definite clues about the imidazole molecule coordination to the metal. The solids formed in the absence of imidazole (3D phases [14] ) contain a single CN stretching band, indicating that the five CN groups form bridges between the metal centers.…”

“…The solids formed in the absence of imidazole (3D phases [14] ) contain a single CN stretching band, indicating that the five CN groups form bridges between the metal centers. [20] These bands are observed at 930, 800, 520, and 480 nm for Fe; 460, 530, and 1040 nm for Co; and 570 and 940 nm for Ni. [19] Such a frequency shift is due to the layered nature of the formed solid and to the binding of the organic ligand to the axial positions for the metal (T).…”

Layered Transition Metal Nitroprussides – Their Preparation, Crystal Structure, and Magnetic Properties

et al. 2016

Divalent transition metal (T) nitroprussides form a series of insoluble coordination compounds, which generally crystallize in 3D frameworks, except for a layered (2D) phase of copper. In this contribution, the preparation of layered phases for T = Mn, Fe, Co, Ni, Zn, and Cd is reported. The incorporation of imidazole (Im) during their preparation by the precipitation method inhibits the coordination of the axial CN groups to the metal T, and layered (2D) structures of formula unit T(Im) 2 [Fe(CN) 5 NO] result. The metal T is found coordinated to the N end of the equatorial CN groups. Imidazole molecules occupy its axial coordination sites. In the interlayer region, imid- [a]

“…Intercalation in some transition metal dichalcogenides has been successfully achieved by chemical transport reactions and electrochemical, ion exchange, and redox methods, in which the embedded substances can be atoms, ions, or molecules [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. In general, the intercalation of various ions or organic molecules into the vdW gap of layered inorganic materials is one of the effective design methods for creating hybrid materials with novel physical properties [ 25 , 26 ].…”

A single crystalline layered semiconductor In1.2Ga0.8S3 phase was grown, and by intercalating p-aminopyridine (NH2-C5H4N or p-AP) molecules into this crystal, a new intercalation compound, In1.2Ga0.8S3·0.5(NH2-C5H4N), was synthesized. Further, by substituting p-AP molecules with p-ethylenediamine (NH2-CH2-CH2-NH2 or p-EDA) in this intercalation compound, another new intercalated compound—In1.2Ga0.8S3·0.5(NH2-CH2-CH2-NH2) was synthesized. It was found that the single crystallinity of the initial In1.2Ga0.8S3 samples was retained after their intercalation despite a strong deterioration in quality. The thermal peculiarities of both the intercalation and deintercalation of the title crystal were determined. Furthermore, the unit cell parameters of the intercalation compounds were determined from X-ray diffraction data (XRD). It was found that increasing the c parameter corresponded to the dimension of the intercalated molecule. In addition to the intercalation phases’ experimental characterization, the lattice dynamical properties and the electronic and bonding features of the stoichiometric GaInS3 were calculated using the Density Functional Theory within the Generalized Gradient Approximations (DFT-GGA). Nine Raman-active modes were observed and identified for this compound. The electronic gap was found to be an indirect one and the topological analysis of the electron density revealed that the interlayer bonding is rather weak, thus enabling the intercalation of organic molecules.
