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.

Dicyclo-hexyl-ammonium bis-(chloro-difluoro-acetato-?O)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.

Dicyclo-hexyl-ammonium bis-(chloro-difluoro-acetato-?O)cyclo-pentyl-diphenyl-stannate(IV).

Project description:The five-coordinate Sn atom in the title mixed organyl stannate compound, (C(12)H(24)N)[Sn(C(5)H(9))(C(6)H(5))(2)(C(2)ClF(2)O(2))], is in a trans-C(3)SnO(2) trigonal-bipyramidal coordination environment. 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.

[Bis-(diphenyl-phosphino)methane-?P,P']dichloridopalladium(II).

Project description:The title complex, [PdCl(2)(C(25)H(22)P(2))], is a slightly distorted square-planar bis-(diphenyl-phosphino)methane cis-complex of PdCl(2). The structure of a polymorph of the title compound has been described earlier, but the arrangement of the mol-ecules observed in the current structure is distinctively different from that previously reported [Steffen & Palenik (1976 ?). Inorg. Chem.15, 2432-2439]. The earlier report describes a structure with individual well separated mol-ecules crystallizing in space group P2(1)/n. The polymorph described here, which is isostructrural to its Pt analogue [Babai et al. (2006 ?). Z. Anorg. Allg. Chem.632, 639-644], crystallizes in C2/c with chains of C2-symmetric mol-ecules stretching parallel to the b axis. The Pd atoms and the bis-phosphino-methane units are located on two different positions created by a non-crystallographic mirror operation with an occupancy of 0.6677?(11) for the major (PCH(2)P)Pd moiety. The positions of the Cl atoms of the minor moiety do coincide perfectly with those of the next mol-ecule along the chain parallel to b, and they are thus not included in the disorder. The phenyl rings also do not take part in the disorder and are common to both the major and minor moieties of the (PCH(2)P)PdCl(2) units. Assuming no defects, mol-ecules in each chain will thus have to be oriented the same way and the effect of the disorder of the (PCH(2)P)Pd unit is thus a reversal in direction of the chains parallel to b. The presence of light streaks of intensity between actual Bragg peaks indicates that a somehow ordered arrangement not resolved in the Bragg diffraction data may be present (i.e. an incommensurate superstructure) rather than a random or domain arrangement of the chains.

A tetra-silver(I)ditungsten(VI) cluster with sulfide and bis-(diphenyl-phosphino)methane ligands.

Project description:The asymmetric unit of the title complex, [Ag(4)W(2)S(8)(C(25)H(22)P(2))(3)]·2C(3)H(7)NO, tris-[?(2)-bis-(diphenyl-phosphino)meth-ane]-3:6?(2)P:P';4:5?(2)P:P';5:6?(2)P:P'-?(5)-sulfido-2:3:4:5:6?(5)S-?(3)-sulfido-1:3:4?(3)S-tetra-?(2)-sulfido-1:3?(2)S;1:4?(2)S;2:5?(2)S;2:6?(2)S-disulfido-1?S,2?S-tetra-silver(I)ditungsten(VI) N,N-dimethyl-formamide disolvate, contains two [WS(4)](2-) anions, four silver cations, three bidentate-bridging bis-(diphenyl-phosphino)methane (dppm) ligands and two N,N-dimethyl-formamide (DMF) solvent mol-ecules. The coordination geometry of each Ag atom is distorted tetra-hedral. Two Ag ions are coordinated by ?(2)-S and ?(5)-S atoms, and by two P atoms from two dppm ligands, while the other two Ag atoms are coordinated by ?(2)-S, ?(3)-S and ?(5)-S atoms, and by one P atom from a dppm ligand.

Bis[?-bis-(diphenyl-phosphino)methane-?P:P']bis-[(4-toluene-sulfonato-?O)silver(I)] monohydrate.

Project description:The title complex, [Ag(2)(C(7)H(7)O(3)S)(2)(C(25)H(22)P(2))(2)]·H(2)O, was obtained by the reaction of silver toluene-sulfonate with diphenyl-phosphinomethane (dppm) in acetonitrile. There are two unique half-mol-ecules of the complex in the asymmetric unit, together with one water mol-ecule, which is disordered over two positions with site occupancy factors of 0.6 and 0.4. In each centrosymmetric neutral dimeric mol-ecule, two Ag atoms are bridged by a pair of dppm ligands to give an eight-membered Ag(2)P(4)C(2) ring with a distorted AgOP(2) trigonal-planar environment. The Ag-Ag distances of 2.9215?(9) and 3.027?(1)?Å indicate a direct bonding inter-action.

Bis[?-1,2-bis-(diphenyl-phosphino)methane-?P:P']bis-[(?-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.

N-[Bis(morpholin-4-yl)phosphino-yl]-2-chloro-2,2-difluoro-acetamide.

Project description:The asymmetric unit of the title compound, C(10)H(17)ClF(2)N(3)O(4)P, consists of two independent mol-ecules in each of which the P atom adopts a distorted tetra-hedral environment with the P=O and N-H units in a syn orientation with respect to one another. Both morpholine rings in one of the phospho-ramide mol-ecules are disordered over two sets of sites, with site occupancies of 0.766?(7) and 0.234?(7) for one ring and 0.639?(10) and 0.361?(10) for the other. In the second phospho-ramide mol-ecule, one of the NC(4)H(8)O moieties is disordered over two sets of sites with site occupancies of 0.807?(6) and 0.193?(6). In the crystal, pairs of inter-molecular N-H?O(P) hydrogen bonds form two independent centrosymmetric dimers.

Project description:In the cation of the title compound, [Ag(4)(C(2)F(3)O(2))(2)(C(12)H(10)O(2)P)(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, the two independent Ag(+) cations are four-coordinated in a distorted tetra-hedral geometry by one P atom from a bis-(diphenyl-phosphan-yl)methane (dppm) ligand, one O atom from a trifluoro-acetate anion and two O atoms from two diphenyl-phosphinate (dpp) ligands. Two dppm ligands, two dpp ligands and two trifluoro-acetate anions bridge four metal atoms, forming a centrosymmetric tetra-nuclear complex. Intra-molecular C-H?O hydrogen bonds and a weak ?-? inter-action [centroid-centroid distance = 3.9804?(13)?Å] are also observed.
