cis-Dichloridobis[diphenyl(4-vinylphenyl) phosphane-kP]platinum(II)

Transition metal complexes containing phosphine, arsine and stibine ligands are widely being investigated in various fields of organometallic chemistry (Spessard & Miessler, 1996). As part of a systematic investigation involving complexes with the general formula trans/cis-[MX2(L)2] (M = Pt or Pd; X = halogen, Me, Ph; L = group 15 donor ligand), the crystals of the title compound, were obtained. [PtCl2(L)2] (L = tertiary phosphine, arsine or stibine) complexes can conveniently be prepared by the substitution of 1,5-cyclooctadiene (COD) from [PtCl2(COD)]. The title compound, cis-[PtCl2{P(4—H2C=CHC6H4) Ph2}2], crystallizes in the triclinic spacegroup P1, with the Pt atom on a center of symmetry and each pair of equivalent ligands in a cis orientation. The geometry is a slightly distorted square planar and the Pt atom is slightly elevated out of the coordinating atom plane. The two P atoms are closer to each other but away from the two chloride atoms with angles of P1—Pt—P2 = 96.1 (4)° and Cl1—Pt—Cl2 = 87.7 (4)° whereas the P1—Pt—Cl1 is = 175.1 (4)° and that of P1—Pt—Cl2 being 89.6 (4)° The title compound compares well with other closely related PtII complexes from the literature containing two chloro and two tertiary phosphine ligands in a cis geometry. The title compound, containing Pt—Cl bond lengths of 2.3566 (9) and 2.3336 (9) Å and Pt—P bond distances of 2.2489 (9) and 2.2627 (9) Å, fits well into the typical range for complexes of this kind. Notably the title compound did not crystallise as a solvated complex; these type of PtII complexes have a tendency to crystallise as solvates (Meijboom & Omondi, 2011). Large thermal vibrations on the periphery of the molecule results in a badly defined C═C bond length. Disordered modelling resulted in an unstable refinement

trans-Dichloridobis{[4-(dimethyl­amino)­phen­yl]diphenyl­phosphane}palladium(II)

The title compound, trans-[PdCl2{PPh2(4-Me2NC6H4)}2], crystallizes with the Pd atom on a center of symmetry, resulting in a distorted trans-PdCl2P2 square-planar geometry. The Pd—P and Pd—Cl bond lengths are 2.3550 (7) and 2.2906 (7) Å, respectively. Some weak inter­actions are observed between the aromatic rings of adjacent mol­ecules, with an inter­planar distance between two π-stacked rings of 3.505 (3) Å. Intra- and intermolecular C—H⋯Cl hydrogen bonds also occur

In the title Pd¹¹ complex, [Pd(C₃H)C₂₆l(CH₂₂NP)], the Pd¹¹ atom is coordinated in a slightly distorted square-planar geometry by the imino N and phosphane P atoms of the ligand, by one chloride ion and by a methyl ligand. The methyl group is trans to the N atom of the ligand

Bis(dicyclo­hexyl­phenyl­phosphine)iodido­silver(I) pyridine monosolvate

The structure of the title compound, [AgI(C18H27P)2]·C5H5N, shows a trigonal-planar coordinated AgI atom within a distorted IAgP2 donor set. The pyridine solvent mol­ecule is only associated with the complex via very weak inter­molecular C—H⋯N inter­actions
