2- and 4-benzylpyridine complexes with bivalent metal halides and pseudohalides

Summary Coordination compounds formed by the interaction of 2- and 4-benzylpyridines with some bivalent metal halides and pseudohalides have been prepared and characterized by molecular conductance, magnetic susceptibility, electronic and i.r. spectral measurements down to 200 cm-1 in the solid state. Tentative stereochemistries for the complexes isolated in the solid state are suggested. The ligand-field parameters 10 Dq, B, , and v2 /v, are calculated for the cobalt(II) and nickel(II) complexes and are consistent with their proposed stereochemistries.
