Abstract

The reaction of Co(NCS)₂ with L produces the coordination polymers of [Co(NCS)₂L₂] unit (L=bis(3-pyridyl) cyclotetramethylenesilane (bpcms) and bis(3-pyridyl)dimethylsilane (bpdms)). Each L linker connects two cobalt(II) ions defining the edges of a 32-membered [Co^II]₄, thus forming a 2D grid sheet structure. The local geometry of the cobalt(II) ion is an octahedral arrangement with two NCS groups in trans position and four pyridine units in a propeller fashion building the basal plane. Difference between dimethyl and cyclotetramethylene moieties of two spacer ligands induces delicate structural difference. The Co-N-CS angle of [Co(NCS)₂(bpdms)₂] is severely bent (Co-N-C=153.9(2)°) in contrast to the corresponding angle (Co-N-C=180.0°) of [Co(NCS)₂(bpdms)₂]. The degree of the Co-N-CS angle seems to be determined by steric or packing effects rather than electronic effects.
