Concerted coordination and hydrogen-bonding network of the 1,4-di-4-pyridyl-2,3-diaza-1,3-butadiene [Zn(MeOH)2(H2O)2](ClO4)2 3:1 complex.
In the title compound, diaquabis(1,4-di-4-pyridyl-2,3-diaza-1,3-butadiene)dimethanolzinc(II) bis(perchlorate) 1,4-di-4-pyridyl-2,3-diaza-1,3-butadiene methanol 1.72-solvate 1.28-hydrate, [Zn(C12H10N4)2(CH4O)2(H2O)2](ClO4)2.C12H10N4.1.72CH4O.1.28H2O, determined at ca 110 K, the Zn cation and the extended dipyridyl ligand both lie across inversion centres in space group P-1. The structure consists of a network arrangement of the constituent species stabilized by a combination of coordination, hydrogen bonding and pi-pi forces. Uncoordinated methanol and water solvent molecules occupy the otherwise void spaces within and between the networks.
