Di­aqua­{μ₂-N,N′-bis­[(cyclo­hexa­nyl­idene)amino]­oxamide}­bis­(tri­phenyl­phosphane)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).

[1H-1,2,4-Triazole-5(4H)-thione-κS]bis­(tri­phenyl­phosphane-κP)(nitrato-κO)silver(I) methanol monosolvate

In the title complex, [Ag(NO₃)(C₂H₃N₃S)(C₁₈H₁₅P)₂]·CH₃OH, the Ag^I ion exhibits a distorted tetra­hedral coordination geometry formed by two P atoms from two tri­phenyl­phosphine ligands, one S atom from a 1H-1,2,4-triazole-5(4H)-thione ligand and one O atom from a nitrate ion. In the crystal, complex and solvent mol­ecules are linked by O—H...O and N—H...O hydrogen bonds forming a chain along the b-axis direction. The chains are linked by weak C—H...O hydrogen bonds forming a two-dimensional supra­molecular architecture parallel to (001). In addition, an intra­molecular N—H...O hydrogen bond is observed.

(N,N′-Di­ethyl­thio­urea-κS)tris­(triphenylphosphane-κP)silver(I) acetate methanol monosolvate

In the mononuclear title complex, [Ag(C₅H₁₂N₂S)(C₁₈H₁₅P)₃](CH₃COO)·CH₃OH, the Ag^I ion is in a distorted tetra­hedral coordination geometry formed by three P atoms from three tri­phenyl­phosphane ligands and one S atom from an N,N′-di­ethyl­thio­urea ligand. In the crystal, the acetate anion is connected to the complex mol­ecule via a pair of N—H...O hydrogen bonds [graph-set motif R²₂(8)] and the solvent methanol mol­ecule is connected to the anion via an O—H...O hydrogen bond. This aggregate is further connected through a weak C—H...O hydrogen bond, forming a chain along [100]. In addition, sixfold phenyl embraces with inter­molecular distances of 6.6463 (13)–6.667 (2) Å are arranged in a chain along [001]. The combination of hydrogen bonding and phen­yl...phenyl inter­actions leads to the formation of a two-dimensional network parallel to (010).

(Aceto­nitrile-κN)iodidobis(tri­phenylphosphane-κP)copper(I)

In the mononuclear title complex, [CuI(CH₃CN)(C₁₈H₁₅P)₂], the Cu^I ion is in a distorted tetra­hedral geometry, coordinated by two P atoms of two tri­phenyl­phosphane ligands, one N atom of an aceto­nitrile ligand and one iodide anion. The aceto­nitrile ligand is disordered over two sets of sites in a 0.629 (15): 0.371 (15) ratio. In the crystal, weak C—H...I hydrogen bonds link the mol­ecules, forming a chain along [100].
