Source of material

All chemicals and solvents were used as purchased without purification. The melting point of the compound was measured on a Mel-Temp II digital melting point apparatus and was uncorrected. The IR spectrum was recorded on a Perkin-Elmer RX1 spectrophotometer in the range 4000 to 400 cm−1.

The dithiocarbamate salt, K[S2CN(Ph)CH2CH2OH], was prepared in situ (methanol) from the reaction of CS2 (Merck, 0.25 mmol) with 2-anilinoethanol (Merck, 0.25 mmol) and KOH (0.03 mL; 50% w/v); CS2 was added dropwise into the methanolic solution (10 mL). The resulting mixture solution was kept at 273 K for 0.5 h. Dimethyltin dichloride (0.25 mmol, 0.05 g) in methanol (10 mL) was added to the prepared salt. The resulting mixture was stirred and refluxed for 2 h. The filtrate was evaporated slowly until a white precipitate was formed. The precipitate was recrystallised from methanol and dimethylformamide. The title molecule was isolated as a side-product obtained from the slow evaporation of the solvent. Yield: 0.02 g (16%). M.pt: >573 K. IR (cm−1) 467 (w) ν(Sn—O), 1487 (m) ν(C—N), 1018 (s) ν(C—O).

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.95–0.99 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The N-bound H-atom was located in a difference Fourier map but was refined with a distance restraint of N—H = 0.88 ± 0.01 Å, and with Uiso(H) set to 1.2Ueq(N).

Comment

Diorganotin dichloride molecules are well-known to be subject to hydrolysis [5], [6] and it was in this context the crystals of the title tetra-tin oxido-cluster {[(Me2SnCl)(Me2Sn)(OCH2CH2N(H)Ph)]O}2, (I), was isolated. The difficulties associated with hydrolysis notwithstanding, recent work has highlighted the potential anti-tumour activity of related tetra-tin oxido clusters [7], [8], a well-documented attribute of organotin compounds [9]. Herein, the crystal and molecular structures of (I) are described.

The molecular structure of (I) is shown in the figure (70% displacement ellipsoids; unlabelled atoms are related by the symmetry operation (i) 1 − x, −y, 1 − z); the entire molecule is generated by the application of a crystallographic centre of inversion. The molecule is constructed about a central Sn2O2 core, containing endocyclic Sn2 atoms. The μ3-O1 oxido atom of the core also binds to an exocyclic Sn1 atom. Further links between the Sn1 and Sn2 atoms are provided by a μ2-O2 alkoxide atom. The coordination geometry for the Sn1 atom is completed by two methyl groups and a chloride atom [Sn1—Cl1 = 2.5866(9) Å], while that of the Sn2 atom is completed by two methyl substituents. Within the core, the Sn2—O1, O1i bond lengths of 2.049(2) and 2.118(2) Å, respectively, and the O1—Sn2—O1i = 73.76(10)° and Sn2—O1—Sn2i = 106.24(10)° bond angles indicate the core has the shape of a distorted rhombus. The Sn1—O2 [2.176(3) Å] and Sn2—O2 [2.181(3) Å] bond lengths indicate the μ2-O(alkoxide) bridge is symmetric. Each of the penta-coordinate geometries is highly distorted. For the Sn1 atom, the donor set is defined by C2ClO2 atoms with the widest angle defined by the Cl1 and O2 atoms [Cl1–Sn1—O2 = 157.89(7)°] whereas for the Sn2 atom, the widest angle in the C2O3 geometry is defined by the O2 and O1i atoms [O2—Sn2—O1i = 146.31(9)°]. The next widest angles are subtended by the tin-bound methyl substituents [C1—Sn1—C2 = 138.66(15)° and C3—Sn2—C4 = 135.40(16)°]. The value of τ is a parameter that quantifies five-coordinate geometries, equalling 0.0 for an ideal square-pyramidal coordination geometry and 1.0 for an ideal trigonal-bipyramid [10]. In (I), τ = 0.32 for the Sn1 atom and τ = 0.18 for the Sn2 atom, each indicative of tendancies towards a square-pyramidal coordination geometry. The sequence of three edge-shared Sn2O2 rhombi have the shape of a kinked ladder.

The most prominent feature of the molecular packing is the formation of amine-N—H⋯Cl hydrogen bonds [N1—H1n⋯Cl1ii: H1n⋯Cl1ii = 2.57(3) Å, N1⋯Cl1ii = 3.461(3) Å with angle at H1n = 177(2)° for (ii) 1 − x, 1 − y, 1 − z]. These give rise to a linear supramolecular chain along the b-axis direction. The chains are linked into a supramolecular layer in the bc-plane by weak methylene-C—H⋯π(phenyl) interactions [C5—H5⋯Cg(C7–C12)iii: H5⋯Cg(C7—C12)iii = 2.79 Å, C5⋯Cg(C7—C12)iii = 3.766(4) Å with angle at H5 = 170° for (iii) 1 − x, −1/2 + y, 1/2 − z]. Layers stack along the a-axis without significant directional interactions between them.

Finally, the Hirshfeld surfaces and two-dimensional fingerprint (full and decomposed) plots were calculated on the entire tetra-tin oxido-cluster using Crystal Explorer 17 [11] and standard procedures [12]. This analysis points to the significance of H⋯H contacts which contribute 76.0% of all contacts to the Hirshfeld surface. The only other two contacts registered are C⋯H/H⋯C [12.7%] and Cl⋯H/H⋯Cl [10.9%].
