Cd(SPh)2 (2) crystallizes unsolvated from DMF with a structure (orthorhombic, P212121, a = 15.490 (2) A, b = 15.626 (2) A, c = 20.803 (3) A, Z = 16 (CdS2C12H10), 3626 observed data, Mo Kα, R = 0.034) in which adamantanoid cages comprised of four Cd atoms and six doubly bridging SPh ligands are connected in three dimensions by doubly bridging SPh ligands. The lattice arrangement of the linked tetrahedral adamantanoid cages is almost identical with that of the α-cristobalite form of SiO2. The structure of crystalline Cd(SC6H4Me-4)2 (3) (monoclinic, P21/c, a = 27.196 (9) A, b = 15.722 (5) A, c = 37.046 (13) A, β = 132.03 (1)°, Z = 32 (CdS2C14H14), 12003 observed data with (sin θ)/λ > 0.1 A-1, Mo Kα, R = 0.065) is also three-dimensionally nonmolecular with vertex-linked adamantanoid tetrahedra, but in a very different linkage pattern involving closed four-, six-, and eight-membered rings of tetrahedra, resembling microporous zeolite lattices. In 3 there exist very large centrosymmetric cavities in the Cd,S array, surrounded by 12 adamantanoid cages whose centroids constitute a trans truncated octahedron. Channels encycled by eight-membered rings also exist in the lattice. The cavities are lined with 44 S atoms connected by 32 Cd atoms, contain 10 ligand substituents, and are connected through four- and six-membered rings to other cavities. Within the cavities the S - S diagonals through the inversion center range from 16.6 to 19.1 A. The volumes excluded by the Cd,S cores of the adamantanoid tetrahedra are 12% and 10% of the unit cell volumes in 2 and 3, respectively, and the remaining volumes occupied by the substituents are partially empty. Both of these poly-linked-adamantanoid structures are unique.

Cd(SC6H5)2 forms a series of 1:1, 1:2, and 2:1 adducts with neutral bidentate nitrogen donors, via reaction in N,N-dimethylformamide solution, but Cd(SC4H9-n)2 does not react under these or other conditions. On the other hand, Cd(SC4H9-n)2 readily reacts with CS2 to give the corresponding bis(thioxanthate), which forms stable adducts; in contrast, Cd(SC6H5)2 reacts only slowly to give Cd(SC6H5)2CS2, which can also be prepared by direct electrochemical oxidation. The mechanism of these reactions is discussed. The crystal structure of Cd(S2CSC4H9-n) 2·2,2′-bipyridine, Cd(S3C5H9)2·C 10H8N2, is monoclinic, with a = 22.184 (3) A?, b = 9.001 (2) A?, c = 12.687 (6) A?, β = 99.90 (3)°, V = 2,550.8 A?3, Z = 4, and space group C2/c; R = 0.025, and T = 20 °C. The molecule has a distorted CdS4N2 kernel, with bond distances of 2.664 (1) and 2.704 (1) A? (Cd-S) and 2.363 (3) A? (Cd-N); the thioxanthate ligand is bidentate. Cd(SR)2 reacts with R′COCl to give the corresponding R′COSR thio esters in good yield.
Interaction of thiosilanes and disilthianes with some transitional and post-transitional metal halides
Abel,Jenkins
, p. 285 - 289 (2007/10/18)
Thiosilanes and disilthianes do not form stable co-ordination complexes with transitional and post-transitional metal halides, but invariably undergo fission of the silicon-sulphur bonds to give alkyl/arylmercaptides, sulphides or sulphonium derivatives o
