Di-μ-thio-semicarbazide-κ(4)S:S-bis-[chlori-dobis(triphenyl-phosphane-κP)silver(I)]

Crystal structure of bis-[μ-bis-(di-phenyl-phosphan-yl)methane-κ(2) P:P']-μ-chlorido-chlorido-1κCl-(1-phenyl-thio-urea-2κS)disilver aceto-nitrile hemisolvate

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag⋯Ag separation of 3.2064 (2) Å. In the crystal, complex mol-ecules are linked by N-H⋯Cl hydrogen bonds forming a dimer. The dimers are linked via weak C- H⋯Cl hydrogen bonds forming a two-dimensional supra-molecular architecture in the yz plane. In addition, an intra-molecular N-H⋯Cl hydrogen bond is observed.

Di-aqua-{μ2-N,N'-bis-[(cyclo-hexa-nyl-idene)amino]-oxamide}-bis-(tri-phenyl-phosphane)silver(I) dinitrate

The dinuclear title compound, [Ag₂(C₁₄H₂₂N₄O₂)(C₁₈H₁₅P)₂(H₂O)₂](NO₃)₂, lies across an inversion center and consists of two [Ag(H₂O)(PPh₃)] units bridged by a bis­(cyclo­hexa­none)oxalydihydrazone ligand. The charge-balance is supplied by two nitrate anions. The symmetry-unique Ag^I ion is in a distorted tetra­hedral geometry coordinated by a P atom from a tri­phenyl­phosphane ligand, an O atom from a water mol­ecule and a bis­(cyclo­hexa­none)oxalydihydrazone ligand bidentate chelating through the O atom and one of N atoms. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the components, forming chains along the b-axis direction. These chains are connected through weak C—H⋯O hydrogen bonds, leading to the formation of a two-dimensional supra­molecular network parallel to (001).
