Four new complexes [L2Cu(S2COC2H5)] {L=PPh3 (A), C3H4N2 (B)}, [L2IrCl2(S2COC2H5)] (L=PPh3) (C) and [L2Pd(S2COC2H5)] (L=PPh3) (D) have been synthesized by the insertion of CS2 in L2CuCl2, L3IrCl3 and L2PdCl2, respectively in mixed solvent of dichloromethane and ethanol at room temperature. The complexes have been characterized by FTIR, UV-visible and ESR spectroscopy. All the complexes have been found to be air-stable. Complexes (A), (B) and (D) are distorted square planar while complex (C) is of distorted octahedral geometry.

Insertion reaction of carbon disulfide with bis(triphenyl phosphine), bis(triphenyl arsine) or bis(triphenyl stibine) copper(I) chloride in a mixed solvent of dichloromethane and ethanol results in the formation of new class of copper (I) complexes of the type [L2Cu(S2COEt)] (L = PPh3, AsPh3 and SbPh3). These three new complexes have been characterized by chemical analysis, DTA, TGA and infrared spectroscopic method. The molar conductances of these complexes are measured in dichloromethane (10-3 M) at room temperature.

We present a simple, easily scalable route to monodisperse copper sulfide nanocrystals by the hot injection of a series of novel copper(I) xanthate single-source precursors [(PPh3)2Cu(S2COR)] (R = isobutyl, 2-methoxyethyl, 2-ethoxyethyl, 1-methoxy-2-propyl, 3-methoxy-1-butyl, and 3-methoxy-3-methyl-1-butyl), whose crystal structures are also reported. We show that the width of the obtained rods is dependent on the length of the xanthate chain, which we rationalize through a computational study, where we show that there is a relationship between the ground-state energy of the precursor and the copper sulfide rod width.
Reactivity of copper(I) tetrahydroborates toward CS2 and SCNPh. Structures of (PPh3)2Cu(μ-S2CSCH2SCS 2)Cu(PPh3)2, (PPh3)2Cu(S2COEt), and (PPh3)2Cu(S2CNHPh)·CHCl3

The reactivity of the copper(I) tetrahydroborate complexes (PPh3)2Cu(BH4) (1), (PCy3)2Cu(BH4) (2), (triphos)Cu(BH4) (3) [triphos = 1,1,1-tris((diphenylphosphino)methyl)ethane], and (np3)Cu(BH4) (4) [np3 = tris(2-(diphenylphosphino)ethyl)amine] toward CS2 and SCNPh has been investigated. Compound 1 reacts with CS2 to give the dinuclear copper(I) complex (PPh3)2Cu(μ-S2CSCH2SCS 2)Cu(PPh3)2 (6), whose molecular structure has been established by single-crystal X-ray diffraction methods. Crystal data: C75H62Cu2P4S6, monoclinic, space group C2/c, Z = 8, a = 53.573 (30) A?, b = 12.759 (9) A?, c = 22.856 (15) A?, β = 104.6 (1)°, final R factor of 0.092 for 4573 observed reflections. In the dimeric molecule, two (PPh3)2Cu fragments are held together by a bridging S2CSCH2SCS22- ligand, formed from a double head-to-tail condensation of three CS2 molecules. The crystal structure of the xanthate complex (PPh3)2Cu(η2-S2COEt) (7) obtained by the solvolysis of 6 in CH2Cl2/ethanol has been determined. Crystal data: C39H35CuOP2S2, monoclinic, space group P21/n, Z = 4, a = 20.299 (14) A?, b = 18.636 (12) A?, c = 9.282 (8) A?, β = 95.5 (1)°, final R factor of 0.052 for 2660 observed reflections. Dithioformate complexes are obtained when 3 and 4 are reacted with CS2. Phenyl isothiocyanate reacts with the present copper(I) tetrahydroborates to give the corresponding N-phenyldithiocarbamate complexes. The crystal structure of (PPh3)2Cu(η2-S 2CNHPh)·CHCl3 (10) has been determined. Crystal data: C44H37Cl3CuNP2S2, triclinic, space group P1, Z = 2, a = 14.772 (11) A?, b = 13.105 (11) A?, c = 12.332 (9) A?, α = 115.9 (1)°, β = 97.1 (1)°, γ = 95.7 (1)°, final R factor of 0.070 for 3635 observed reflections.
