	Title	S4X4 and its Derivatives: Preparation. Structure and Thermolysis of CuBr * S4X4
	Abstract	The crystalline black polymeric Cui complex CuBr • S4N4 can be prepared in high yield from Cu(NÜ3)2 • 3 HoO, NH4Br and S4N4 in methanol. An X-ray structure analysis shows that it is isostructural with CuCl • S4N4. The crystals contain [CuBr]^ chains and the Cu atoms of adjacent chains are bridged by S4N4 groups. The Cu atoms have an almost tetrahedral coordination. Tho l,3-N,N'-bonded S4N4 group has the same conformation and, within narrow limits, the same dimensions as free S4N4. Thermolysis of CuBr • S4N4 at 180 C C yields among other products CuBr, S4N4, and S2N2.

	Title	Kupfer-und Goldkomplexe von Dithiocarbaminsäureestern. Strukturen von [CuC1(L1)3] * CH2C12, [AuC1(L1)2], [CuI(L1)(PPh3)]2 und [Cu2ICuIICl4(L2)2]IJ (L1 = N-Phenyl-S-methyldithiocarbaminsäureester, L2 = N,N-Dimethyl-S-methyldithiocarbaminsäureester) N-Phenyl-S-methyldithiocarbamate, L2 = N,N-Dimethyl-S-methyldithiocarbamate)
	Abstract	Copper and Gold Complexes of Dithiocarbam ate Esters. X-Ray Structures of [CuC1(L1)3] ■ CH2C12, [A uC ^L 1^], [CuI(L1)(PPh3)]2 and [Cu2ICuIICl4(L2)2]n (L 1 = Reactions of N-phenyl-S-methyldithiocarbamate (L1) and N,N-dimethyl-S-methyldithio-carbamate (L2) with CuCl2, [CUjI^PPhj^] and HAuC14 yield the complexes [CuC1(L1)3] • CH2C12 (1), [AuCKL1),] (2), [CuI(L1)(PPh3)]2 (3) and [Cu2ICuIICl4(L2)2]" (4). Their structures have been determined by single crystal X-ray crystallography. 1 and 2 are monomeric, with Cu(I) tetrahedrally four-coordinate and Au(I) two-coordinate with an S-Au-S angle of 158.2(1)°. 3 is dimeric with a central CuI2Cu core, the Cu— Cu distance of which [314.9(1) pm] is rather large. The mixed valence complex 4 has a chain structure with the identity period CuI1(a-Cl)2CuI(a-S)2CuI(a-Cl)2. Cu1 is in a tetrahedral, Cu11 in a square planar environment. The (m-S)2 bridged Cu1---Cu1 distance is only 259.1(1) pm. The structures of the CuX2Cu cores of 3 and 4 are mainly determined by steric interactions of the donor atoms within the coordination spheres of the metal centers.
