ABSTRACT
The title compound, [Zn(C(19)H(12)N(5))(2)], crystallizes in the tetragonal space group P4(3)2(1)2, with the monomer residing on a twofold axis. The imidazole N-bound H atoms are disordered over the two positions, with refined occupancies of 0.59â
(3) and 0.41â
(3). The strong similarities to, and slight differences from, a reported P4(2)2(1)2 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.
