Abstract

The title complex, [Ni(SO4)(C19H17N7)]·2H2O or [Ni(SO4)(dpdapt)]·2H2O [dpdapt is 6‐phenyl‐2,4‐bis(2‐pyridylamino)‐1,3,5‐triazine], has a distorted trigonal–bipyramidal coordination where the equatorial plane contains the N atoms of the pyridine rings and one of the O atoms of the sulfate group, while the axial positions are occupied by the other O atom and the N atom of the triazine ring of the dpdapt ligand. The complex lies across a mirror plane. The H atoms of the NH group of the dpdapt ligand and of the solvent water molecule are involved in hydrogen bonds, which form an infinite two‐dimensional corrugated sheet parallel to the ac plane. The water molecule is disordered over two positions; the site occupancy factors are 0.58 and 0.42.
