Two novel ligand pyrazole derivatives AH and BH (AH = [(3,5-dimethyl-1H-pyrazole-1-yl)methyl]amino acetic acid, BH = [bis-(3,5-dimethyl-1H-pyrazole-1-yl)methyl]amino acetic acid) formed simultaneously by the condensation of N-hydroxy methyl-3,5-pyrazole (1) with glycine (CH 3 COOH) and their cobalt(II) or copper(II) mixed ligand complex, with 3,5-dimethyl-1H-pyrazole (Pz) have been synthesized and characterized by spectroscopic analysis and X-ray diffraction study. Distorted square pyramidal geometry is observed around copper(II) with two nitrogens (N 1 , N 3 of AH) in the first plane and third nitrogen (N4 of one pyrazolic ligand) and two oxygen atoms (O 4 and O 1 ) in the second plane. In contrast to Cu(II) cation which coordinates with ligand AH, the Co(II) cation prefers to coordinate with the second ligand BH.
