Project description:The asymmetric unit of the title compound, [Pd(2)Cl(2)(C(20)H(26)P)(2)]·2CH(2)Cl(2), contains one half-mol-ecule of the palladium complex and a dichloro-methane solvent mol-ecule. In the complex, two Pd(II) atoms are bridged by two Cl atoms, with the other two coordination sites occupied by a C atom of the biphenyl system and a P atom, resulting in a distorted square-planar coordination geometry of the Pd(II) atom and a cyclo-metallated four-membered ring. The Pd(2)Cl(2) unit is located about an inversion center. The planes of the rings of the biphenyl system make a dihedral angle of 66.36 (11)°.
Project description:The title compound, [PtCl2(C26H22P2)]·2CHCl3 (I), is the third monoclinic polymorph of this platinum(II) complex involving the bidentate ligand cis-1,2-bis-(di-phenyl-phosphan-yl)ethyl-ene (cis-dppe) [for the others, see: Oberhauser et al. (1998a ▸). Inorg. Chim. Acta, 274, 143-154, and Oberhauser et al. (1995 ▸). Inorg. Chim. Acta, 238, 35-43]. The structure of compound (I) was solved in the space group P21/c, with one complex mol-ecule in the asymmetric unit along with two solvate chloro-form mol-ecules. The PtII atom is ligated by two P and two Cl atoms in the equatorial plane and has a perfect square-planar coordination sphere. In the crystal, the complex mol-ecule is linked to the chloro-form solvate mol-ecules by C-H⋯Cl hydrogen bonds and face-on C-Cl⋯π inter-actions. There are also weak offset π-π inter-actions present [inter-centroid distances are 3.770 (6) and 4.096 (6) Å], linking the mol-ecules to form supra-molecular sheets that lie in the bc plane.
Project description:In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag⋯Ag separation of 3.2064 (2) Å. In the crystal, complex mol-ecules are linked by N-H⋯Cl hydrogen bonds forming a dimer. The dimers are linked via weak C- H⋯Cl hydrogen bonds forming a two-dimensional supra-molecular architecture in the yz plane. In addition, an intra-molecular N-H⋯Cl hydrogen bond is observed.
Project description:The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclo-metalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloro-methane solvent mol-ecules create C-H⋯Cl inter-actions with the metal complex, generating supermolecular layers in the ab plane. Additional C-H⋯π and π-π [centroid-centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] inter-actions join these planes into a three-dimensional supermolecular network.
Project description:The mol-ecular structure of the title compound, trans-[Cu(C2H)Cl(C26H24P2)2], consists of an Ru(II) cation, located on an inversion centre, in an octa-hedral environment defined by two chelating phosphines, one acetyl-ide and one chloride ligand. The -C CH and the chlorine ligands are disordered over two equivalent positions (0.5 occupancy each). The coordination geometry is distorted octa-hedral, with the -C CH fragment and the Cl ligand in trans positions. The four P atoms occupy the equatorial plane of the octa-hedron and the chloride and acetyl-ide ligands the axial positions.
Project description:The PdII central atom in the title complex, [PdCl(C26H24P2)(C6H6N2O)]NO3·CH3CN or [PdCl(dppe)(INAM)]NO3·CH3CN, where dppe is 1,2-bis-(di-phenyl-phosphan-yl)ethane and INAM is isonicotinamide, exists in a slightly distorted square-planar environment defined by the two P atoms of the dppe ligand, a chloride ligand and the N atom of the isonicotinamide pyridyl ring. The crystal packing in the structure is held together by hydrogen bonds between the amide of the INAM ligand and the nitrate ions that complete the outer coordination sphere. A mol-ecule of aceto-nitrile is also found in the asymmetric unit of the title complex.
Project description:A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ▶), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(μ-P)(2) core (r.m.s. deviation = 0.003 Å). The Pd-Pd distance of 2.5988 (5) Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.
Project description:Dimeric mol-ecules of the title compound, [Ru(2)Cl(4)(C(12)H(18))(2)], are located on a crystallographic centre of inversion with one mol-ecule in the asymmetric unit. The hexa-methyl-benzene rings are in an η(6)-coordination to the ruthenium centres, which are bridged by two chloride ligands. In addition, the ruthenium centres are bonded to another chloride ligand. The aromatic rings and the Ru(2)Cl(2) four-membered ring enclose a dihedral angle of 55.85 (6)°.
Project description:The structure of the title compound, [RuCl2(C7H10N2)2(C2H6OS)2], has monoclinic (P21/n) symmetry. The Ru-N distances of the coordination compound are influenced by the trans chloride or di-methyl-sulfoxide-κS ligands. The mol-ecular structure exhibits disorder for two of the terminal methyl groups of a dimethyl sulfoxide ligand.
Project description:In the title Ru(II) carboxyl-ate compound, [Ru(C2H3O2)(C26H24P2)2](CF3O3S)0.75Cl0.25, the distorted tris-bidentate octa-hedral stereochemistry about the Ru(II) atom in the complex cation comprises four P-atom donors from two 1,2-bis-(diphenyl-phosphan-yl)ethane ligands [Ru-P = 2.2881 (13)-2.3791 (13) Å] and two O-atom donors from the acetate ligand [Ru-O = 2.191 (3) and 2.202 (3) Å]. The disordered counter-anions are located on the same site in the structure in a 3:1 ratio, the expanded formula comprising four complex cations, three trifluoro-methane-sulfonate anions and one chloride anion, with two such formula units in the unit cell.
