“…Nakamoto andco-workers (31) in their recent paper have assigned Co-N stretching at 266 and 228 cm-' and we tentatively assign our bands at 265 and 232 cm-' as Co-N, while the 204 c m ' absorption band is due to Hg-S stretching. The Co-N stretching band is further confirmed by Strukl and Walter (32) who assigned it at 270 cm-I in their bipyridine complex. Similarly in our phenanthroline complex we tentatively assign 287 and 245 cm-I to Co-N stretching and 215 cm-' to Hg-S stretching.…”

A new series of octahedral cobalt(II) complexes are formed when CoX2(X = Cl, Br, I, SCN) reacts with Hg(SCN)2 in the presence of Lewis bases. These complexes of stoichiometry CoHg(SCN)4•2L (L = THF, dioxane, pyridine, aniline) are pink to violet solids which slowly decompose to the blue crystalline solid, CoHg(SCN)4, the stable magnetic susceptibility standard. On further reaction of CoHg(SCN)4•2THF with mono-, bi-, and polydentate ligands in dry ethanol, complexes of the following types are obtained: CoHg(SCN)4•2L (L = PΦ3), CoHg(SCN)4•2LL (LL = trien), CoHg(SCN)4•3LL (LL = en, bipy), and CoHg(SCN)4•4LL (LL = phen). The stoichiometry of these were determined by elemental analysis. Possible structures of these are discussed with the help of mid and far infrared, visible, and ultraviolet spectroscopy, magnetic susceptibility, and X-ray powder diffraction. Some new i.r. bands like Co—P, Co—N, and Hg—S are assigned in the low region.

“…The ligand 2,2-bipy has a bidentate chelating coordination site with which it can coordinate metal [34] and metal-oxide [35] particles, clays [36] and transition metal ions [37][38][39]. In the current work, Cu(OH) 2 was functionalised with 2,2-bipy, and analysis for bipy-Cu(OH) 2 was consistent with a Cu(OH) 2 :2,2-bipy ratio of $44:1.…”

The coordiantion compounds [Zn(C 10 H 8 N 2 ) (Cl 2 HCCOO)(H 2 O) 3 ] -Á[Zn(C 10 H 8 N 2 )(Cl 2 HCCOO) 3 ] ? and [Cd(C 10 H 8 N 2 ) 2 (Cl 2 CHCOO) 2 ] were synthesised and characterised by elemental and thermal analysis, IR and UV-VIS spectroscopy, and X-ray crystallography. The complexes are air stable and well-soluble in water. The zinc atoms are five and six coordinated and the cadmium atom is six coordinated. The coordination polyhedra of central atoms can be described as trapezoidal pyramid and octahedron in zinc compound and as rectangular bipyramid strongly distorted towards skew trapezoidal bipyramid in cadmium compound. In both compounds all dichloroacetate groups are monodentate. The bond valences considerations show that all 2,2 0 -bipyridine molecules are bonded almost 2 times stronger than carboxylate groups. In the structure of zinc compound exist O-HÁÁÁO hydrogen bonds and in both structures can be found weak C-HÁÁÁO hydrogen bonds. Additionally, both compounds are pile-stacked by pÁÁÁp interactions. The IR spectra show typical vibrations for chelating 2,2 0 -bipyridine molecules and terminal monodentate carboxylate groups. The thermal decomposition studies show zinc compound decomposes in 4 steps and cadmium compound decomposes in 5 steps with formation of oxides as a final products. The ligands decompose gradually, first dichloroacetates and next 2,2 0 -bipyridine.
