μ‐Bi­phenyl‐2,2′‐di­thiol­ato‐κ2S:S′‐bis­[(tri­phenyl­phosphine‐κP)­gold(I)]

The reaction of ClAuPPh₃ and 1,1′‐bi­phenyl‐2,2′‐di­thiol in the presence of tri­methyl­benzyl­ammonium chloride and K₂CO₃ in a tetra­hydro­furan/methanol solution gives the title complex, [Au₂(C₁₂H₈S₂)(C₁₈H₁₅P)₂]. The mol­ecule contains P—Au—S units which `cross' with torsion angles of ∼90° [P—Au—Au—P = 86.23 (5)° and S—Au—Au—S = 95.62 (5)°]. The intra‐ and intermolecular Au⋯Au distances [3.9064 (3) and 6.3797 (5) Å, respectively] are outside the range for typical Au⋯Au interactions. However, the Au atoms appear to be drawn together, leading to a significant bending of the P—Au—S angles [170.24 (5) and 169.52 (5)°].

Tris(ethyl­ene­diamine)­nickel(II) bis­[2‐cyano‐2‐(oxidoimino)­acetamidato]­nickelate(II) monohydrate

The title compound, [Ni(C₂H₈N₂)₃][Ni(C₃HN₃O₂)₂]·H₂O, appears to be a modular associate consisting of two complex counter‐ions, containing bivalent nickel as the central atom in both cases, and a solvent water mol­ecule. The Ni^II ion in the complex cation lies on the C₂ crystallographic axis. Its coordination environment is formed by six N atoms of three ethyl­ene­diamine (en) mol­ecules, representing a distorted octa­hedral geometry. The Ni^II ion in the complex anion occupies a position at the center of inversion. It exhibits a distorted square‐planar coordination geometry formed by four N atoms belonging to the deprotonated oxidoimine and amide groups of the two doubly charged 2‐cyano‐2‐(oxidoimino)acetamidate anions, situated in trans positions with respect to each other. In the crystal packing, the complex anions are linked by water mol­ecules via hydrogen bonds between the amide O atoms and water H atoms, forming chains translated along the a direction. The [Ni(en)₃]²⁺ cations fill empty spaces between the translational chains, connecting them by hydrogen bonds between the oxime and amide O atoms of the anions and the amine H atoms of the cations, forming layers along the ac plane. The water mol­ecules provide connection between layers through N atoms of the cations, thus forming a three‐dimensional modular structure.

In the complex, each Mn²⁺ ion is coordinated by three O atoms and one N atom from the pyridine‐2,6‐di­carboxyl­ate ligands and by three water O atoms, resulting in a distorted pentagonal bipyramidal coordination. Within the centrosymmetric dinuclear complex, two Mn²⁺ ions are bridged by two carboxyl­ate O atoms. The crystal structure is stabilized by hydrogen bonds involving all the H atoms of the water ligands.
