Trans-Dibromidobis[tris-(4-chloro-phen-yl)phosphine]palladium(II).

ABSTRACT: In the title compound, [PdBr(2)(C(18)H(12)Cl(3)P)(2)], the Pd(II) ion is situated on a centre of symmetry and is coordinated by two Br anions [Pd-Br = 2.4252 (2) Å] and two P-donor ligands [Pd-P = 2.3317 (6) Å] in a slightly distorted square-planar geometry [P-Pd-Br = 86.589 (15)°].

trans-Dichloridobis[tris-(2-methoxy-phen-yl)phosphine]palladium(II).

Project description:The structure of the title compound, [PdCl(2)(C(21)H(21)O(3)P)(2)], shows a nearly square-planar geometry for the Pd(II) atom within the Cl(2)Pd[P(PhOMe)(3)](2) ligand set. The Pd(II) atom sits on a centre of inversion and therefore the asymmetric unit contains one half-mol-ecule, i.e. half of one Pd(II) atom, one Cl atom and one tris-(2-methoxy-phen-yl)phosphine ligand.

trans-Dibromidobis[diphen-yl(p-tol-yl)phosphine]palladium(II).

Project description:In the title compound, [PdBr(2)(C(19)H(17)P)(2)], the Pd(II) ion resides on a centre of symmetry and is coordinated by two Br anions [Pd-Br = 2.4266 (2) Å] and two P-donor ligands [Pd-P = 2.3462 (5) Å] in a slightly distorted square-planar geometry [P-Pd-Br = 93.528 (12)°]. Weak inter-molecular C-H⋯Br hydrogen bonds link mol-ecules into chains extended in [10].

trans-Dibromidobis(triphenyl-phosphine-?P)palladium(II) chloro-form monosolvate.

Project description:The Pd(II) atom in the title compound, [PdBr(2){P(C(6)H(5))(3)}(2)]·CHCl(3), lies on a twofold rotation axis and is coordinated in a distorted square-planar geometry by two P atoms from two triphenyl-phosphine ligands and by two Br atoms in a trans arrangement. The chloro-form solvent mol-ecule is equally disordered about another twofold rotation axis.

trans-Dichloridobis[tris-(4-methoxy-phen-yl)phosphine]palladium(II) benzene monosolvate.

Project description:The structure of the title compound, [PdCl(2)(C(21)H(21)O(3)P)(2)]·C(6)H(6), shows a square-planar geometry for the Pd(II) atom within a Cl(2)[P(PhOMe)(3)](2) ligand set. The crystal structure contains benzene as solvent. The Pd(II) atom sits on a centre of inversion and therefore the asymmetric unit contains the Pd(II) atom, one Cl atom, one tris-(4-methoxy-phen-yl)phosphine ligand and one half of the benzene solvent mol-ecule.

trans-Dibromidobis(1-ethyl-3-methyl-imidazol-2-yl-idene)palladium(II).

Project description:The title compound, trans-[PdBr(2)(C(6)H(10)N(2))(2)], was synthesized ionothermally in the ionic liquid solvent 1-ethyl-3-methyl-imidazolium bromide. In the crystal, the Pd(II) atoms are square-planarly coordinated to two Br atoms and two neutral (C(6)H(10)N(2)) ligands. The Pd(II) atom is located on an inversion centre.

Dichlorido(?-toluene)[tris-(4-methoxy-phen-yl)phosphine]ruthenium(II).

Project description:In the title compound, [RuCl(2)(C(7)H(8))(C(21)H(21)O(3)P)], the Ru(II) atom possesses a pseudo-octa-hedral geometry and the metrical parameters around the metallic core compare well with those of similar three-legged-piano-stool complexes.

Tris(2-methoxy-phen-yl)phosphine.

Project description:In the title compound, C(21)H(21)O(3)P, the whole mol-ecule is disordered over two sets of positions with refined occupancies of 0.503?(1) and 0.497?(1). The dihedral angles between the three benzene rings are 72.9?(2)°, 82.9?(3)° and 70.0?(2)° in the major disorder component and the corresponding angles in the minor disorder component are 85.0?(2)°, 79.2?(2)° and 72.3?(2)°. The crystal structure is stabilized by C-H?? inter-actions.

trans-Dibromidobis(tri-p-tolyl-arsine)palladium(II).

Project description:In the title compound, [PdBr(2)(C(21)H(21)As)(2)], the Pd(II) ion, residing on a centre of symmetry, is coordinated by two As donor atoms [Pd-As = 2.4276?(2)?Å] and two Br anions [Pd-Br = 2.4194?(2)?Å] in a distorted square-planar geometry [Br-Pd-As = 87.786?(7)°]. A weak intra-molecular C-H?Br inter-action occurs. In the crystal structure, inter-molecular C-H?Br inter-actions are observed.
