A new polymorph of bis[2,6-bis(1H-benzimidazol-2-yl-κN 3)pyridinido-κN]zinc(II)

The title compound, [Zn(C19H12N5)2], crystallizes in the tetragonal space group P43212, with the monomer residing on a twofold axis. The imidazole N-bound H atoms are disordered over the two positions, with refined occupancies of 0.59(3) and 0.41(3). The strong similarities to, and slight difference...

Descripción
Sumario:The title compound, [Zn(C19H12N5)2], crystallizes in the tetragonal space group P43212, with the monomer residing on a twofold axis. The imidazole N-bound H atoms are disordered over the two positions, with refined occupancies of 0.59(3) and 0.41(3). The strong similarities to, and slight differences from, a reported P42212 polymorph which has a 50% smaller unit-cell volume [Harvey, Baggio, Muñoz & Baggio (2003). Acta Cryst. C59, m283-m285], to which the present structure bears a group-subgroup relationship, are discussed. © 2013 International Union of Crystallography.
