The ligand di-2-pyridyl ketone oxime (dpko) is known for bridging and cluster complexes with first-row transition metal centers. We have previously synthesized and structurally characterized chloro derivatives of zinc and copper complexes with this ligand. Our current research focuses on first-row transition metal complexes with different halide ligands and counterions. Here we present the synthesis and analysis of a variety of dpko complexes with Mn2+, Fe3+, Co3+, Ni2+, and Zn2+ in a variety of solvents and varying reaction conditions. We analyzed all novel complexes via IR and electronic spectroscopies, magnetic susceptibility, and�where appropriate�X-ray crystallography. Here we present the fully-resolved X-ray structure of Zn(dpko)Br2, which exhibits a disorder at the oxime group
