Source of materials

Crystals of the title compound were prepared in accord with the literature procedure [6]. Recrystallisation succeeded by layering an ethanol solution of the compound with diethyl ether. The harvested crystals were analysed directly and found to exhibit unit cell parameters that differed from literature precedents [6, 7] .

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.99 Å) and refined as riding with Uiso(H) = 1.2Ueq(C). The O-bound H-atoms were located in difference Fourier maps, but were refined with a distance restraint of O—H = 0.84 + −0.01 Å, and with Uiso(H) set to 1.5Ueq(O). The maximum and minimum residual electron density peaks are located 1.07 and 0.63 Å from the Zn atom.

Discussion

There are two distinct structural motifs for the binary zinc(II) dithiocarbamates of the general formula Zn(S2CNRR′)2 [8]. When the steric bulk of R/R′ is relatively great, monomeric species with tetrahedral zinc coordination geometries are found. The majority of the structures are binuclear, owing to the presence of equal numbers of both chelating and μ2-bridging dithiocarbamate ligands.

As seen from the figure (70% displacement ellipsoids; unlabelled atoms are related by the symmetry operation: − x, −y, 1 − z). The title complex is binuclear and features a symmetry independent chelating dithiocarbamate ligand which forms disparate Zn—S1, S2 bond lengths of 2.3426(7) and 2.4230(8) Å. The second dithiocarbamate ligand is bridging, forming an almost symmetric bridge, with Zn—S3, S4i bond lengths of 2.3650(7) and 2.3202(7) Å, while at the same time forming a somewhat weaker transannular Zn—S3i bond length of 3.0458(9) Å. The resultant S5 donor set is a square pyramid as judged from the value of τ = 0.16 cf. 0.0 and 1.0 for ideal square-pyramidal and trigonal-bipyramidal geometries, respectively [9]. In this description the S1, S2, S3i, S4i atoms define the basal plane with a r.m.s. deviation of 0.0009 Å. The zinc atom lies 0.7400(5) Å above this plane in the direction of the S3 atom. Overall, the conformation of the Zn2S4 core is that of a chair or step-ladder.

Significant hydrogen bonding is present in the crystal. Thus, hydroxyl-O–H⋯O(hydroxyl) hydrogen bonding involving three of the hydroxyl groups is found [O1—H1o⋯O3: 1.98(4) Å and 169(5)°; O3—H3o⋯O2: 1.87(4) Å and 167(4)°; and O4–H4o⋯O1i: 2.01(3) Å and 166(4)° for symmetry operation i: −1 + x, −1 + y, z]. Two of these interactions are intramolecular while one is intermolecular. The fourth hydroxyl group forms an intramolecular hydroxyl-O—H⋯S(dithiocarbamate) hydrogen bond [O2—H2o⋯S1: 2.76(4) Å and 121(4)°]. Such hydroxyl-O—H⋯S(dithiocarbamate) hydrogen bonds are not unusual for dithiocarbamate ligands functionalised with hydroxyethyl groups [10]. The result of the hydrogen bonding is a supramolecular chain parallel to [1 1 0].

There are two known polymorphs for {Zn[S2CN(CH2CH2OH)2]}2. The first report was of a monoclinic (C2/c) form [7] and the second of an orthorhombic (Pbcn) one [6]. The common feature of all polymorphs is the centrosymmetric, binuclear structure and chair conformation of the Zn2S4 core. The differences between the polymorphs relate primarily to the supramolecular patterns. Thus, in both of the known polymorphs, only hydroxyl-O—H⋯O (hydroxyl) hydrogen bonding is observed. In the C2/c form [7], flat supramolecular layers are formed while in the Pbcn form [6], layers are undulating.
