Abstract
- Four new solvent-induced Co(II) complexes with chemical formulae [{CoL(μ<subscript>2</subscript>-OAc)(MeOH)}<subscript>2</subscript>Co] (1), [{CoL(μ<subscript>2</subscript>-OAc)(EtOH)}<subscript>2</subscript>Co] (2), [{CoL(μ<subscript>2</subscript>-OAc)(Py)}<subscript>2</subscript>Co] (3) and [{CoL(μ<subscript>2</subscript>-OAc)(DMF)}<subscript>2</subscript>Co] (4) (H<subscript>2</subscript>L = 4-nitro-4'-chloro-2,2'-[(1,3-propylene)dioxybis (nitrilomethylidyne)]diphenol) have been synthesized and characterized by elemental analyses, FT-IR, UV-Vis spectra and single-crystal X-ray diffraction. Each of the prepared complexes, crystallizing in the space groups P-1 (1 and 4), P2<subscript>1</subscript>/n (2) and P2<subscript>1</subscript>/c (3), consists of three Co(II) atoms, two completely deprotonated (L)<subscript>2-</subscript> units, two μ-acetato ligands and two coordinated solvent molecules. Although the four complexes 1-4 were synthesized in different solvents, it is worthwhile that the Co(II) atoms in the four complexes 1-4 adopt hexa-coordinated with slightly distorted octahedral coordination geometries, and the ratio of the ligand H<subscript>2</subscript>L to Co(II) atoms is 2:3. The complexes 2-4 possess a self-assembled infinite 1D, 2D and 1D supramolecular structures via the intermolecular hydrogen bonds, respectively. Magnetic measurement was performed in the complex 3.
