In the crystal structure of the title compound, [Cu(C4H4NO4S)2(C2H8N2)2], the Cu2+ ion resides on a centre of symmetry. The environment of Cu2+ ion is a distorted octahedron. The axial bond lengths between the CuII ion and the N atoms are considerably longer than the equatorial bond distances between the CuII ion and the N atoms of the ethylenediamine ligand as a consequence of the Jahn–Teller effect. The molecular conformation is stabilized by intramolecular N—H
O hydrogen bonds. In the crystal, molecules are connected by intermolecular N—HO hydrogen bonds into chains running along the a axis.

In the title compound, C12H17N3O2S, the 4-methyl-2-methylsulfanyl-6-oxo-1,6-dihydropyrimidine-5-carbonitrile part of the molecule is almost planar (r.m.s deviation = 0.062 Å). In the crystal, molecules form centrosymmetric dimers via pairs of N—HO hydrogen bonds.

In the title molecule, C18H16N2O3, the five-membered ring has an envelope conformation, with the substituted C atom deviating by 0.342 (4) Å from the mean plane P calculated for the remainder of the non-H atoms of the 2,3-dihydro-1H-indene fragment. The mean planes of quinazoline-2,4(1H,3H)-dione fragment and P form a dihedral angle of 59.08 (4)°. In the crystal, pairs of N—HO hydrogen bonds link molecules into inversion dimers, and weak C—HO hydrogen bonds and π–π interactions between the benzene rings of the quinazoline ring systems [centroid–centroid distance = 3.538 (3) Å] further consolidate the packing.
