Synthesis, Characterization, and Crystal Structure of a Supramolecular CoII Complex Containing Salen-Type Bisoxime
摘要:
A supramolecular CoII complex, [CoL(H2O)2], bearing Salen-type bisoxime chelate ligand 4,4,6,6-tetrachloro-2,2-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H2L), has been synthesized and structurally characterized by elemental analyses, IR spectra, UVvis spectra, and X-ray diffraction techniques. The crystal structure of [CoL(H2O)2] indicates that the CoII complex consists of one CoII atom, one L2 unit, and two coordinated water molecules. The CoII complex exhibits slightly distorted octahedral geometry with the Salen-type bisoxime ligand forming the basal N2O2 coordination plane and two oxygen atoms from the coordinated water molecules in the axial positions. An infinite 1D metalwater chain and 2D supramolecular network structure were formed by intermolecular O-H center dot center dot center dot O, O-H center dot center dot center dot Cl, and C-H center dot center dot center dot O hydrogen bonding and - stacking interactions.
