Dichlorido[2-(3,5-dimethyl-1H-pyrazol-1-yl-κN2)ethanamine-κN]zinc(II)

Abstract

The amine title complex, [ZnCl2(C7H13N3)], resulted from imine hydrolysis in a Schiff base compound. The Zn metal atom has a distorted tetrahedral geometry with the most significant deviation identified in the magnitude of the N—Zn—N angle. This deviation stems from the participation of the Zn and N atoms in a six-membered metallocyclic ring. The latter is in an approximate screw-boat conformation. Two strong N—H...Cl hydrogen bonds link the molecules into ribbons propagating along the b-axis direction. The ribbons contain two second-order hydrogen-bonded motifs: a chain and a ring. The chain described by the graph set notation C22(6) is formed by one hydrogen bond going in the forward direction (donor to acceptor) and the other in the backward direction (acceptor to donor). In the ring motif R22(8), both hydrogen bonds propagate in the forward direction.
