Trans-Bromido(pyrimidinyl-?C)bis-(triphenyl-phosphane-?P)palladium(II).

ABSTRACT: In the title complex, [PdBr(C(4)H(3)N(2))(C(18)H(15)P)(2)], the geometry around the Pd atom is distorted square-planar with the Pd atom displaced by 0.0334?(14)?Å from the BrP(2)C plane. The two Ph(3)P ligands are in trans positions, defining a P-Pd-P angle of 171.78?(5)°, while the pyrimidinyl and bromide ligands are trans to each other [C-Pd-Br = 174.63?(14)°].

trans-Iodido(pyrazinyl-?C(2))bis-(triphenyl-phosphane-?P)palladium(II).

Project description:There are two independent mol-ecules with similar configurations in the asymmetric unit of the title complex, [Pd(C(4)H(3)N(2))I(C(18)H(15)P)(2)]. In each mol-ecule, the geometry around the Pd atom is distorted square-planar, with the Pd atom displaced by 0.0549?(12) and 0.0734?(13)?Å from the least-squares plane of the I-P-P-C atoms. The PPh(3) ligands are in trans positions, with P-Pd-P angles of 173.12?(4) and 170.29?(4)°, while the pyrazinyl ligands and I atoms, also trans to each other, form C-Pd-I angles of 179.38?(12) and 178.44?(12)°. In the crystal, C-H?? inter-actions occur, resulting in a three-dimensional supramolecular architecture.

trans-Chlorido(phenanthren-9-yl)bis-(triphenyl-phosphane)nickel(II).

Project description:The title compound, [Ni(C(14)H(9))Cl(C(18)H(15)P)(2)], was synthesized from the reaction between 9-chloro-phenanthrene, NiCl(2)·6H(2)O and triphenyl-phosphane in ethanol. The bond angles around the Ni(II) atom indicate that it exists in a slightly distorted square-planar geometry.

trans-Dichloridobis(triphenyl-phosphane-?P)palladium(II) benzene hemisolvate.

Project description:The title complex, [PdCl(2)(C(18)H(15)P)(2)]·0.5C(6)H(6), has the Pd(II) ion in a square-planar coordination mode (r.m.s. deviation for Pd, P and Cl atoms = 0.024?Å) with the PPh(3) and Cl ligands mutually trans. The benzene solvent mol-ecule is located about a crystallographic inversion centre. The title complex is isostructural with trans-dichloridobis(triphenyl-phosphane)-palladium(II) 1,4-dichloro-benzene sesquisolvate [Kitano et al. (1983 ?). Acta Cryst. C39, 1015-1017].

Di-?-iodido-bis-[(biphenyl-2-yl)(triphenyl-phosphane-?P)palladium(II)].

Project description:In the title compound, [Pd2(C12H9)2I2(C18H15P)2], the dimeric complex mol-ecule lies about an inversion center. The Pd?I?Pd bridges are slightly asymmetric, with Pd-I distances of 2.6709?(6) and 2.7486?(7)?Å. The metal atom has a slightly puckered square-planar CI2P environment, the largest deviation from the least-squares plane being 0.143?(8)?Å.

Bis(methyl xanthato)-κS;κS:S'-(triphenyl-phosphane-κP)palladium(II).

Project description:The title compound, [Pd(C(2)H(3)OS(2))(2)(C(18)H(15)P)], features a palladium complex with a triphenyl-phosphane ligand and two xanthate ligands, one of them coordinates in a bidentate and the other in a monodentate fashion, giving rise to a slightly distorted square-planar coordination of the Pd(II) ion. As a result of this difference in the coordination modes, the C-S bond lengths are different, viz. 1.687 (2) and 1.692 (2) Å in the bidentate ligand and 1.723 (2) Å in the monodentate ligand, whereas the non-coordinating S atom has a C-S distance of 1.649 (2) Å. The crystal packing is stabilized by C-H⋯O inter-actions.

cis-(Pyridin-2-ylcarbonimidodithio-ato-?S,S')bis-(triphenyl-phosphane-?P)palladium(II).

Project description:The title compound, [Pd(C(6)H(4)N(2)S(2))(C(18)H(15)P)(2)], was obtained as a minor product from the reaction of trans-PdCl(2)(PPh(3))(2) with piperazine-1,4-dicarbothioic acid bis-(pyridin-2-yl)amide.

The crystal structure features weak ?-? [centroid-centroid distance =3.7327(15)?Å] and C-H?? inter-actions and contains an almost spherically shaped void of 50.4?Å(3) per unit cell.

(1-Acetyl-thio-urea-?S)bromido-bis(triphenyl-phosphane-?P)silver(I).

Project description: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.

Project description:In the title compound, trans-[PdCl(2){P(4-MeOC(6)H(4))(3)}(2)]·C(7)H(8), the Pd(II) atom lies on a center of symmetry, resulting in a distorted trans-square planar geometry.

In the crystal, weak C-H?O inter-actions are observed between the aromatic rings of adjacent mol-ecules. The toluene solvate molecule is equally disordered over two sets of sites.
