AbstractThe title compound, [Zn2(C42H38N9O3)2(NO3)2]·2CH3CN·0.5H2O, is a bis-phenolate-bridged dinuclear ZnII complex. The asymmetric unit comprises half the zinc complex (the full complex is completed by the application of a centre of inversion), one acetonitrile solvent molecule and a quarter of a water molecule (located on a twofold axis with half-occupancy; H atoms were not located for this molecule). Each triazine-based multidentate ligand uses a phenolate group to bridge ZnII ions, generating a Zn2O2 core. The ZnII ions are five-coordinate, with an additional long Zn-O contact [2.6465 (16) Å], and include a semi-bidentate nitrate ion and a N,N',O-tridentate mode of the ligand in the coordination sphere. Non-coordinating pyridine groups form intramolecular O-HN hydrogen bonds with phenol groups. As suggested by the short O--O donor-acceptor distances between the disordered water molecules and phenol O atoms, these groups also participate in hydrogen bonding.
