The preparation and spectroscopic characterization of a series of dmtp complexes of Zn, Cd, and Hg, where dmtp is 5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidine, is reported. Crystal structure analyses of [Zn(dmtp)2Br2] and [Hg(dmtp)2Cl2] reveal distorted tetrahedral geometries about the central atoms and the dmtp
