The ligand 2, 6-bis (benzimidazol-2-yl)-4-hydroxypyridine (H3OBP) and its complexes,[Co (HOBP)(H2OBP)]· 2H2O· 2EtOH (1) and [Ni (H2OBP) 2][Ni (H3OBP)(H2OBP)] NO3· 3H2O (2), have been synthesized and characterized by single-crystal X-ray crystallography, IR, UV- Vis, and fluorescence spectroscopies. Each metal center in two complexes is six- coordinated with N6 donor set in slightly distorted octahedral environment, which are ...
