Dicarbonyl-dichloridobis(trimethyl-phosphane)iron(II)-carbonyl-dichlorido-tris(trimethyl-phosphane)iron(II)-tetra-hydro-furan (1/1/2).

ABSTRACT: The asymmetric unit of the title crystal, [FeCl(2)(C(3)H(9)P)(3)(CO)]·[FeCl(2)(C(3)H(9)P)(2)(CO)(2)]·2C(4)H(8)O, contains half mol-ecules of the two closely related Fe(II) complexes lying on mirror planes and a tetra-hydro-furan solvent mol-ecule, one C atom of which is disordered over two sets of sites with site occupancy factors 0.633 (9) and 0.367 (9). In both Fe(II) complex mol-ecules, a distorted octa-hedral coordination geometry has been observed around the Fe atoms. Weak intermolecular C-H⋯O inter-actions are observed in the crystal structure.

Project description:The title compound, [PdCl(2)(C(21)H(33)P)(2)], forms a monomeric complex with a trans-square-planar coordination geometry about the Pd(II) atom which lies on an inversion centre.

Project description:In the title complex, [Mo(C(7)H(5)OS)Cl(C(18)H(15)P)(2)(CO)(2)], the geometry around the metal atom is a capped octa-hedron. The phen-oxy-thio-carbonyl ligand coordinates the Mo(II) atom through the C and S atoms. A one-dimensional structure is formed by ?-? inter-molecular inter-actions and a supra-molecular aggregation is determined by inter-molecular C-H?O, C-H?Cl, C-H??(arene) hydrogen bonds and CO??(arene) inter-actions [O?centroid distances = 3.485?(4) and 3.722?(3)?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.

Project description:In the title compound, [PtCl2(C21H21O3P)2]·2C3H6O, the asymmetric unit contains a Pt(II) ion situated on an inversion center, one chloride anion, one tris-(4-meth-oxy-lphen-yl)phosphane (L) ligand and one acetone solvent mol-ecule.

The effective cone angle of the phosphane ligand was calculated to be 156°. Weak C-H?O and C-H?Cl hydrogen bonds hold mol-ecules together.

Dichlorido(3-phenyl-indenyl-idene)bis-(triphenyl-phosphane)ruthenium(II) tetra-hydro-furan disolvate.

Project description:The Ru(II) atom in the title compound, [RuCl(2)(C(15)H(10))(C(18)H(15)P)(2)]·2C(4)H(8)O, has a distorted square-pyramidal conformation. The P and Cl atoms are at the base of the pyramid and the Ru-C(indenyl-idene) bond is in the axial position. The two Cl ligands and the two phosphane ligands are in trans positions. The Cl-Ru-Cl and P-Ru-P angles are 157.71?(2) and 166.83?(2)°, respectively. The two independent tetra-hydro-furan (THF) solvent mol-ecules are disordered. One THF mol-ecule was refined using a split-atom model. The second THF mol-ecule was accounted for by using program PLATON/SQUEEZE [Spek (2009 ?). Acta Cryst. D65, 148-155]. The molecular conformation shows three intramolecular C-H?Cl contacts and two C-H?? interactions while the crystal packing features an intermolecular C-H?Cl contact and two very weak intermolecular C-H?? contacts.

[8-(Diphenyl-phosphan-yl)naphthyl-?C,P](phenyl-ethyn-yl)tris-(trimethyl-phosphane-?P)iron(II).

Project description:The title compound, [Fe(C(8)H(5))(C(22)H(16)P)(C(3)H(9)P)(3)], was synthesized by the addition of phenyl-ethine to a solution of the parent methyl iron complex Fe(CH(3)){P(C(6)H(5))(2)(C(10)H(6))}(PMe(3))(3) at 213?K, accompanied by evolution of methane. The coordination around the iron center can be described as slightly distorted octa-hedral [Fe-P 2.2485?(12)-2.2902?(12)?Å; Fe-C 1.918?(5), 2.015?(4)?Å], with a meridional arrangement of the trimethyl-phosphine ligands and the introduced terminal alkinyl-ligand trans to the P(Ph)(2)-anchoring group.

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)].
