Reactions of 1,1,2,3,4,5,6-heptahydro-1,1-dihalido telluranes [(C 5H10TeX2), X = Cl, Br, I] with sodium/ammonium (dialkyl/aryl dithiocarbamates) viz. NaS2CN(C2H 5)2, NH4S2CNC4H 8O, NH4S2CNC5H10, NH 4S2CNHC6H5 yield new [C 5H10TeI{S2CN(C2H5) 2} (1), C5H10TeI(S2CNC 4H8O) (2), C5H10TeI(S 2CNC5H10) (3), C5H 10TeBr{S2CN(C2H5)2} (4), C5H10TeBr(S2CNC4H8O) (5), C5H10TeBr(S2CNC5H10) (6), C5H10TeCl{S2CN(C2H 5)2} (7), C5H10TeCl(S 2CNC4H8O) (8), C5H 10TeCl(S2CNC5H10) (9), C 5H10TeCl(S2CNHC6H5) (10), C5H10Te{S2CN(C2H5) 2}2 (12), C5H10Te(S 2CNC4H8O)2 (13), C5H 10Te(S2CNC5H10)2 (14)] complexes. The substitution reaction of C5H10TeCl 2 with NH4S2CNHC6H5 yields complex (10) along with the cleaved product SC(NHC6H 5)2 (11). In such type of substitution reaction, the formation of SC(NHC6H5)2 H5C 6HN-CS∥-NHC6H5 (11) is uncommon. The probable pathway for obtaining the cleaved product has been postulated on the basis of a comparative account with other similar type of cleavage reactions. The intermolecular Te?S secondary bonds and/or C-H?X (X = O, Cl, I) hydrogen bonds lead to the formation of (stairs, zig-zag ribbons), trimeric, tetrameric, hexameric and decameric supramolecular assemblies. The complexes have been characterized by elemental analysis, IR and (1H, 13C, 125Te) NMR spectroscopy and single crystal X-ray crystallography of 1, 2, 4, 7, 8, 9 and 11.
