Crystal structure of [3-(4,5-di­hydro-1,3-thia­zolin-2-yl-κN)-1,3-thia­zolidine-2-thione-κS (2)](1,3-thia­zol­idine-2-thione-κS (2))copper(I) nitrate

The mononuclear complex salt, [Cu(C(3)H(5)NS(2))(C(6)H(8)N(2)S(3))]NO(3), contains a [C(9)H(13)CuN(3)S(5)](+) cation and an NO(3) (−) anion. All of the non-H atoms of the cation lie on a mirror plane, as do the N and one O atom of the nitrate anion, such that the planes of the cation and anion are mutually orthogonal. The cationic complex adopts a slightly distorted trigonal–planar geometry about the Cu(I) cation. In the crystal, layers parallel to (010) are generated by N—H⋯O hydrogen bonds, supported by short S⋯O [3.196 (4) and 3.038 (3) Å] and S⋯S contacts [3.4392 (13) Å]. Adjacent layers are linked by C—H⋯O hydrogen bonds and weak π–π stacking inter­actions [centroid–centroid distance = 4.0045 (10) Å] between the thia­zoline rings, forming a three-dimensional network. This stacking also imposes a close contact, of approximately 3.678 Å, between the Cu(I) cations and the centroids of the six-membered chelate rings of mol­ecules in adjacent layers.
