Trans-Dichloridobis[dicyclo-hex-yl(4-isopropyl-phen-yl)phosphane-?P]platinum(II) acetone monosolvate.

ABSTRACT: The title compound, [PtCl(2)(C(21)H(33)P)(2)]·C(3)H(6)O, crystallizes with an accompanying acetone solvent mol-ecule. The metal atom shows a distorted square-planar coordination environment, with a P-Pt-P angle of 172.41?(3)° as the most prominent feature. Both isopropyl fragments were treated as disordered over two conformations with occupancy ratios of 0.55?(2):0.45?(2) and 0.58?(2):0.42?(2). The solvent mol-ecule was also disordered over two orientations in a 1:1 ratio. The crystal studied was a non-merohedral twin with a twin component of 32.4%.

Project description:The title compound, [PdCl(2){P(C(6)H(11))(2)(C(6)H(5))}(2)], forms a monomeric complex with a trans-square-planar geometry.

One of the cyclo-hexyl rings is disordered with the phenyl ring in a 0.587?(9):413?(9) ratio. Five long-range C-H?Cl inter-actions were observed within the structure.

Project description:In the title complex, trans-[PtCl2{P(C6H11)2(4-Me2NC6H4)}2]·2CH2Cl2, the Pt(II) atom is located on an inversion centre, resulting in a trans-square-planar geometry.

The effective cone angle for the dicyclo-hex-yl[4-(dimethyl-amino)-phen-yl]phosphane unit was calculated to be 164°. The compound crystallizes with two dichloro-methane solvent mol-ecules; one of which is severely disordered and was treated using the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

Project description:The title compound, [PtCl(2)(C(20)H(20)P)(2)]·C(4)H(8)O(2), crystallizes with the Pt atom in a distorted cis-square-planar geometry.

trans-Dichloridobis{tris-[4-(trifluoro-methyl)phen-yl]phosphane-?P}palla-dium(II) dichloro-methane monosolvate.

Project description:The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the Pd(II) atom situated on an inversion centre) and a dichloro-methane molecule in the asymmetric unit. The independent Pd(II) atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl-Pd-P angles ranging from 86.151?(19) to 93.849?(19)° are evident. The effective cone angles for the tris-[4-(trifluoro-meth-yl)phen-yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C-H?Cl/F inter-actions create a three-dimensional supramolecular network. Loose packing at two of the -CF3 groups resulted in large thermal vibrations which were treated as two-component disorders [occupancy ratios 0.50:0.50 and 0.628?(15):0.372?(15)].
