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

The amine title complex, [ZnCl₂(C₇H ₁₃N₃)], resulted from imine hydrolysis in a Schiff base compound. The Zn metal atom has a distorted tetra-hedral 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 C₂ ²(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.
