ABSTRACT
In the title compound, [Zn(C8H5N5O3)(C12H8N2)(H2O)]·3H2O, a tridentate 2-amino-7-methyl-4-oxidopteridine-6-carboxyl-ate ligand, a bidentate ancillary 1,10-phenanthroline (phen) ligand and a water mol-ecule complete a distorted octa-hedral coordination geometry around the Zn(II) 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 mol-ecules and lattice water mol-ecules 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.
