【 摘 要 】

In the title compound, [Zn(C8H5N5O3)(C12H8N2)(H2O)]·3H2O, a tridentate 2-amino-7-methyl-4-oxidopteridine-6-carboxyl­ate ligand, a bidentate ancillary 1,10-phenanthroline (phen) ligand and a water mol­ecule complete a distorted octa­hedral coordination geometry around the ZnII atom. The pterin ligand forms two chelate rings. The phen and pterin ring systems are nearly perpendicular [dihedral angle = 85.16 (5)°]. Classical N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds and weak C—H⋯O hydrogen bonds link the complex mol­ecules and lattice water mol­ecules into a three-dimensional network. π–π stacking contacts are observed as well, with centroid-to-centroid distances of 3.5679 (14), 3.7004 (14), 3.6641 (15), 3.6974 (13) and 3.3412 (12) Å.
