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.

A comparative study on 4-(4-(3-mesityl-3-methylcyclobutyl)thiazole-2-yl)-1-thia-4-azaspiro[4.5]decan-3-one: Experimental and density functional methods

“…In the thiazolidine ring, S2AC19 and S2AC20 bond lengths are 1.689 (7) and 1.832 (6) Å, respectively. These values are not very different from the SAC single bond length for thiazolidine ring in the literature (1.758 Å) [31]. The thiazole and thiazolidine ring are planar with a maximum deviation of 0.0097 Å. Cyclohexane ring has a chair conformation.…”

“…The synthesis is accompanied by a transformation of the tzdSH (tzdSH: C 3 H 5 NS 2 , thiol form) into a tzdt ligand (tzdt: C 3 H 5 NS 2 , thion form). A similar transformation was described previously by Saithong et al (2014). Metal complexes of thiones and thionates were reviewed by Raper (1997).…”
