Crystal structure of [3-(4,5-dihydro-1,3-thiazolin-2-yl-κN)-1,3-thiazolidine-2-thione-κS2](1,3-thiazolidine-2-thione-κS2)copper(I) nitrate

Abstract

The mononuclear complex salt, [Cu(C3H5NS2)(C6H8N2S3)]NO3, contains a [C9H13CuN3S5]+cation and an NO3−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 CuIcation. 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 CuIcations and the centroids of the six-membered chelate rings of molecules in adjacent layers.
