Bis[?-bis-(diphenyl-phosphino)methane-?P:P']bis-[(chloro-difluoro-acetato-?O)silver(I)](Ag-Ag).

ABSTRACT: The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry. In each complete mol-ecule, two bis-(diphenyl-phosphino)methane ligands bridge two Ag(I) ions, which are further coordinated by one chloro-difluoro-acetate ligand, giving T-shaped geometries and short intra-molecular Ag?Ag distances of 3.1078?(6) and 2.9950?(6)?Å. In one mol-ecule, the unique -CF(2)Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.

Project description:In the title salt, [Ag(C(27)H(26)P(2))(2)][Sn(C(6)H(5))(3)(C(2)ClF(2)O(2))], the Ag(I) atom exists in a tetra-hedral coordination geometry formed by four P atoms [Ag-P = 2.460 (1)-2.501 (1) Å], whereas the Sn(IV) atom exists in a trans-trigonal-bipyramidal coordination geometry formed by two O [Sn-O = 2.208 (3) and 2.233 (3) Å] and three C atoms [Sn-C = 2.115 (4)-2.128 (4) Å;(Σ C-Sn-C)= 360.0 (6)°].

Bis[μ-1,2-bis-(diphenyl-phosphino)methane-κP:P']bis-[(η-ethene)nickel(0)] toluene disolvate.

Project description:In the title compound, [Ni(2)(C(2)H(4))(2)(C(25)H(22)P(2))(2)]·2C(7)H(8), each Ni atom is coordinated in a trigonal-planar geometry by two P atoms of the bridging 1,2-bis-(diphenyl-phosphino)methane (dppm) ligands and by the centroid of the double bond of an ethene ligand. An eight-membered ring comprising the two Ni atoms, four P atoms and the CH(2) groups of the two dppm ligands is thus formed. The methyl group in one of the solvent toluene mol-ecules is disordered over two positions with equal occupancies.

Project description:In the title chain compound, [Ag(NO(3))(C(26)H(24)P(2))](n), the bis-(diphenyl-phosphino)ethane (dppe) units link the Ag(+) ions into chains along [001]. A nitrate anion is coordinated to the Ag atom. There is a centre of symmetry at the mid-point of the ethane C-C bond and a twofold rotation axis passes through the Ag, N and terminal O atoms. Each Ag atom is four-coordinated in a distorted tetra-hedral geometry by two O atoms of the nitrate anion and two P atoms of dppe ligands. The two aromatic rings are oriented at a dihedral angle of 73.77 (3)°.

[μ-1,3-Bis(diphenyl-phosphino)propane-κP:P']bis-[bromidogold(I)].

Project description:The title compound, [Au(2)Br(2)(C(27)H(26)P(2))], features linearly coordinated Au(I) atoms within P,Br-donor sets. The central portion of the mol-ecule is practically planar as quanti-fied by the Br-Au⋯Au-Br torsion angle of -169.9 (2)°. The P-Au-Br chromophores are twisted with respect to each other [dihedral angle = 52.3 (6)°]. The benzene rings on each P atom lie on either side of this plane. The Au atoms are positioned at the periphery of the mol-ecule, which facilitates the formation of Au⋯Au inter-actions [3.2575 (11) Å] that result in the formation of supra-molecular chains along the b-axis direction. The Au⋯Au inter-actions are responsible for the deviations from the ideal linear geometry for each Au atom.

Project description:In the title mononuclear complex, [Ag(C(18)H(18)N(2)P)(NO(3))(2)], the metal centre is coordinated in a slightly distorted trigonal-planar geometry by the P atom of the phosphine ligand and the O atoms of the two monodentate nitrate anions. In the crystal structure, complex mol-ecules are connected by inter-molecular N-H⋯O hydrogen bonds, forming chains running parallel to the b axis.

catena-Poly[silver(I)-bis-[μ-bis-(diphenyl-phosphino)methane-κP:P']-μ-thio-cyanato-κS:S-silver(I)-μ-thio-cyanato-κS:N].

Project description:The title compound, [Ag(NCS)(C(25)H(22)P(2))](n), contains two Ag(+) ions, two thio-cyanate ions and two bis-(diphenyl-phosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag(+) ions in a μ(2)-mode from its S atom and the two dppm ligands bridge the silver ions in a μ(1),μ(1) mode. The remaining SCN(-) ion bridges the binuclear units via its N and S atoms, generating a one-dimensional polymer propagating in [01]: the resulting AgP(2)SN and AgP(2)S(2) coordination geometries could be described as distorted tetra-hedral.

The two C atoms of one of the two eth-oxy groups are disordered and were refined using a split model and site-occupation factors of 0.7:0.3. The crystal structure contains a benzene solvent mol-ecule with a site occupation of 70%.

Dicyclo-hexyl-ammonium bis-(chloro-difluoro-acetato-κO)cyclo-hexyl-diphenyl-stannate(IV).

Project description:In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the hydrogen-bonding inter-actions giving rise to linear hydrogen-bonded chains.

The NH(2) groups of the cations act as hydrogen-bond donors to two symmetry-related anions, resulting in the formation of linear chains. One of the phenyl rings is disordered over two sites with equal occupancies.

trans-Di-μ-acetato-[μ-N,N-bis-(diphenyl-phosphino)aniline]bis-[chlorido-molybdenum(II)](Mo-Mo)-dichloro-methane-tetra-hydro-furan (1/0.3/1.7).

Project description:The mol-ecular structure of the title compound, [Mo(2)(CH(3)COO)(2)Cl(2)(C(30)H(25)NP(2))]·0.3CH(2)Cl(2)·1.7C(4)H(8)O, features an Mo-Mo dumbbell bridged by two acetate groups which are trans to each other. Perpendicular to the plane spanned by the acetate groups, the Ph(2)PN(Ph)PPh(2) ligand bridges both Mo atoms, having a P-N-P angle of 114.09 (19)°. In a trans position to the PNP ligand are two Cl atoms, one on each molybdenum centre. The Mo-Mo bond distance is 2.1161 (9) Å, within the range known for Mo-Mo quadruple bonds. The Mo complex is located on a crystallographic twofold rotation axis which runs through the N-C bond of the ligand. The site occupation factors of the disordered solvent molecules were fixed to 0.15 for dichloromethane and 0.85 for tetrahydrofuran.
