Synthesis and characterization of organophosphine/phosphite stabilized silver(I) methanesulfonates: Crystal structures of [Ph3PAgO3SCH3] and [(Ph3P)2AgO3SCH3]

Assembly of silver-oxo complexes based on N-diphenylphosphanylmethyl-3-aminopyridine and their structures, photocatalysis and photocurrent responses

Compound {[Ag(μ-η²-Sal)(3-dppmapy)]}_n exhibits prompt anodic photocurrent responses and high photocatalytic performance in the degradation of organic dyes.

Crystal structure of cyclo-bis-(μ4-2,2-di-allyl-malonato-κ(6) O (1),O (3):O (3):O (1'),O (3'):O (1'))tetra-kis-(triphenyl-phosphane-κP)tetra-silver(I)

In the tetra-nuclear mol-ecule of the title compound, [Ag4(C9H10O4)2(C18H15P)4], the Ag(I) ion is coordinated by one P and three O atoms in a considerably distorted tetra-hedral environment. The two 2,2-di-allyl-malonate anions bridge four Ag(I) ions in a μ4-(κ(6) O (1),O (3):O (3):O (1'),O (3'):O (1')) mode, setting up an Ag4O8P4 core (point group symmetry -4..) of corner-sharing tetra-hedra. The shortest intra-molecular Ag⋯Ag distance of 3.9510 (3) Å reveals that no direct d (10)⋯d (10) inter-actions are present. Four weak intra-molecular C-H⋯O hydrogen bonds are observed in the crystal structure of the title compound, which most likely stabilize the tetra-nuclear silver core.

(1-Acetyl-thio-urea-κS)bromido-bis(triphenyl-phosphane-κP)silver(I)

In the title complex, [AgBr(C3H6N2OS)(C18H15P)2], the Ag(I) ion is in a distorted tetra-hedral geometry coordinated by two P atoms from two triphenyl-phosphane ligands, one S atom of an acetyl-thio-urea ligand and one bromide ligand. There are intra-molecular N-H⋯Br and N-H⋯O hydrogen bonds present. In the crystal, pairs of N-H⋯S hydrogen bonds involving thio-urea groups form inversion dimers. In addition, moleclues pack to give sixfold phenyl embraces with an inter-molecular P⋯P distance of 6.4586 (17) Å.
