چکیده
The title compound, C(26)H(34)NSi(2) (+)·Cl(-), shows chirality at silicon. Because of its highly selective synthesis with an e.r. of >99:1 by means of a racemic resolution with mandelic acid, the free disilane is of great importance to the chemistry of highly enanti-omerically enriched lithio-silanes and their trapping products. N-H⋯Cl hydrogen bonding is present between the protonated nitro-gen atom of the piperidino group and the chloride counter-anion. The silicon-silicon distance as well as silicon-carbon and carbon-nitro-gen bond lengths are in the same ranges as in other quaternary, functionalized di- and tetra-silanes.

In the crystal structure of the title compound, C(4)H(8)N(2)O(4)·C(18)H(15)OP, two triphenyl-phosphine oxide mol-ecules and two dimethyl hydrazine-1,2-dicarboxyl-ate mol-ecules are connected via N-H⋯O hydrogen bonds of moderate strength and are related via a twofold rotational axis. Weak C(ar)-H⋯ O contacts strengthen the crystal structure.

The title compound, [CuCl(C(3)H(8)N(2)S)(C(18)H(15)P)(2)]·0.5CH(3)CN, was prepared by the reaction of copper(I) chloride with 1,3-dimethyl-thio-urea (dmtu) and triphenyl-phosphine (PPh(3)) in acetonitrile. The Cu(I) atom has a distorted tetra-hedral environment formed by two P atoms from triphenyl-phosphine, one S atom from the dmtu ligand and one Cl atom. In addition, the mol-ecules exhibit in...
