Three complexes [Co(L4)(DMF)(H2O)(NO3)]NO3· DMF·0.5H2O (1), [Co(L4)2(SCN)2]·4CH3OH·H2O (2) and [Cd(L4)(bipy)(H2O)2](ClO4)2·4H2O (3) (DMF = N, N-dimethylformamide, bipy = 4,4′-bipyridine) were synthesized by reactions of ligand 1,3,5-tris(4-pyridylmethoxyl)benzene (L4) with the corresponding metal salts and their structures were determined by X-ray single-crystal structure analysis. Complex 1 crystallizes
