N,N-Bis(diphenyl-phosphan-yl)cyclo--penta-namine.

ABSTRACT: The coordination around the N atom in the title compound, C(29)H(29)NP(2), shows an almost planar geometry, defined by the attached P and C atoms, in order to accomodate the steric bulk of the phenyl rings. The distortion of the trigonal-pyramidal geometry of the N atom is illustrated by the bond angles ranging between 115.22?(12) and 121.76?(9)°. The P atoms present a pyramidal environment with bond angles ranging from 100.62?(9) to 104.71?(8)°. One of the C atoms in the cyclo-pentyl ring displays a 0.822?(4):0.178?(4) positional disorder. Within the crystal structure, intra-molecular C-H?P hydrogen bonds together with inter- and intra-molecular C-H?? inter-actions link the mol-ecules into a supra-molecular two-dimensional network.

Bis[N,N-bis-(diphenyl-phosphan-yl)cyclo-penta-namine-κ²P,P']platinum(II) bis-(trifluoro-methane-sulfonate).

Project description:The title compound, [Pt(C₂₉H₂₉NP₂)₂](CF₃SO₃)₂, consists of a Pt(II) atom, situated on an inversion centre, coordinated by two diphosphinoamine bidentate ligands and charge-balanced by two trifluoro-methane-sulfonate anions. The Pt(II) atom has a distorted square-planar geometry defined by the four P atoms. The distortion is illustrated by the P-Pt-P bite angle of 70.31 (4)°. The geometry around the N atom deviates from a trigonal-planar geometry, evidenced by the P-N-P bite angle of 102.3 (2) °. The N atom is displaced by 0.114 (4) Å from the C/P/P plane. In order to coordinate, the orientation of the phenyl rings alters from a C(s) conformation to a C(2v) conformation. The cyclo-pentane ring is slightly twisted: the puckering parameters are q(2) = 0.420 (5) Å and ϕ = 26.5 (8) °. The trifluoro-methane-sulfonate anion displays a 0.511 (11):0.489 (11) positional disorder. Weak inter- and intra-molecular C-H⋯O hydrogen bonds influence the crystal packing.

μ-Bis(diphenyl-phosphan-yl)borato-κP:P'-bis-[dicarbon-yl(η-cyclo-penta-dien-yl)iron(II)] tetrachloridoferrate(III) chloro-form solvate.

Project description:The title compound, [Fe(2)(C(5)H(5))(2)(C(24)H(22)BP(2))(CO)(4)][FeCl(4)]·CHCl(3), is an oxidation product of CpFe(CO)(2)PPh(2)BH(3). One pair of phenyl rings attached to the two different P atoms are almost parallel, as are the other pair [dihedral angles = 8.7 (5) and 8.9 (5)°]. The planes of the two cyclo-penta-dienyl rings are inclined by 26.8 (7)° with respect to each other. The carbonyl groups at each Fe atom are almost perpendicular [C-Fe-C = 92.6 (6) and 94.3 (5)°].

N,N-Bis(diphenyl-phosphan-yl)cyclo-butanamine.

Project description:In the title compound, C(28)H(27)NP(2), the N atom adopts an almost planar geometry with the two P atoms and the C atom attached to it, with a distance of 0.066?(2)?Å between the N atom and the C/P/P plane. The distorted trigonal-pyramidal geometry of the N atom is further illustrated by bond angles ranging between 115.22?(11) and 123.53?(8)°. Bond angles varying from 99.99?(9) to 108.07?(9) ° are indicative of the distorted pyramidal environment around the P atoms. An intra-molecular C-H?P hydrogen bond occurs. In the crystal, inter-molecular C-H?? inter-actions link the mol-ecules into a supra-molecular network.

Project description:The title phosphane, C(32)H(38)P(4) or (Ph(2)P)(2)P(P(t)Bu(2)), has a P atom that is linked to another three P atoms in a pyramidal configuration; the P-P distances in the range 2.2231 (7)-2.2446 (7) Å indicate that the P-P bonds are single bonds.

Bis(1-{bis-[2-(diphenyl-phosphino-yl)eth-yl]phosphan-yl}-2-(diphenyl-phosphan-yl)ethane)dinitratoplatinum(II) methanol tetra-solvate.

Project description:In the title compound, [Pt(NO(3))(2)(C(42)H(42)O(2)P(4))(2)]·4CH(3)OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the Pt(II) ion, creating, together with four P ligand atoms, a distorted octa-hedral coordination environment. In addition, several close C-H⋯O contacts between the nitrate O atoms and phenyl H atoms are found. Hydrogen bonds from two methanol solvent mol-ecules to one of the O-P groups complete the crystal structure.

[1,2-Bis(diphenyl-phosphino)ethane]-chlorido(?-penta-methyl-cyclo-penta-dien-yl)iron(II) dichloro-methane solvate.

Project description:In the title compound, [Fe(C(10)H(15))Cl(C(26)H(24)P(2))]·CH(2)Cl(2), the Fe(II) atom is coordinated by two P atoms from a 1,2-bis-(diphenyl-phosphino)ethane ligand [Fe-P = 2.2130?(7) and 2.2231?(7)?Å], a chloride anion [Fe-Cl = 2.3329?(7)?Å] and a penta-methyl-cyclo-penta-dienyl (Cp*) ligand [Fe-centroid(Cp*) = 1.732?(3)?Å] in a typical piano-stool geometry. In the crystal structure, the complex and solvent mol-ecules are paired via weak C-H?Cl inter-actions.

[1,2-Bis(dimethyl-phosphino)ethane]carbon-yl(η-cyclo-penta-dien-yl)iron(II) diphenyl-phosphinoylborate.

Project description:In the title compound, [Fe(C(5)H(5))(C(6)H(16)P(2))(CO)](C(12)H(13)BOP), the Fe(II) ion adopts a three-legged piano-stool geometry, with Fe⋯Cg = 1.721 (5)Å (Cg = the centroid defined by the C atoms of the cyclo-penta-dienyl ring). The 1,2-bis-(dimethyl-phosphino)ethane (dmpe) ligand chelates to form a five-membered C(2)P(2)Fe ring which is in a pseudo-half-chair conformation. In the crystal structure, associations of one cation and two anions are formed via weak inter-molecular C-H⋯O hydrogen bonds, giving rise to R(4) (2)(9) rings.

N,N-Bis(diphenyl-phosphan-yl)benzyl-amine.

Project description:In the title compound, C(31)H(27)NP(2), the diphenyl-phosphanyl groups are staggered relative to the PNP backbone. The N atom is displaced by 0.219 (2) Å from the plane formed by the two P atoms and the methylene C atom. The angles around the N atom are 120.84 (16), 113.29 (16) and 120.57 (12)°, indicating that it exhibits a distorted trigonal-pyramidal geometry. There are no classical inter-molecular inter-actions.

[?-Bis(diphenyl-phosphan-yl)acetonitrile-?P:P]bis-[chloridogold(I)].

Project description:The title complex, [Au(2)Cl(2)(C(26)H(21)NP(2))], has an intra-molecular Au?Au inter-action of 3.1669?(4)?Å, but no inter-molecular Au?Au inter-actions in the solid state. The Cl-Au-P bond angle of 176.84?(7)° is slightly distorted from linearity. The P-C bond length to the phenyl group is shorter [1.810?(7)?Å] than the P-C bond length [1.876?(7)?Å] to the bridging carbon, indicative of the flexibility of the bidentate bite of the ligand. The C-C N fragment is essentially linear at 179.5?(9)° and the C N bond length of 1.125?(11)?Å indicates predominantly triple-bond character. In the crystal packing, there are no hydrogen-bonding or aurophilic inter-actions between the mol-ecules.

[1,1'-Bis(diphenyl-phosphan-yl)ferrocene-?(2)P,P'](?(5)-cyclo-penta-dien-yl)(dicyanamido-?N)ruthenium(II) dichloro-methane monosolvate.

Project description:The title compound, [FeRu(C(5)H(5))(C(2)N(3))(C(17)H(14)P)(2)], was obtained by reaction of Cp(dppf)RuCl [dppf = 1,1'-bis-(diphenyl-phosphan-yl)ferrocene] with sodium dicyanamide in dichloro-methane. The Ru(II) atom is capped by an ?(5)-cyclo-penta-dienyl (Cp) ring, a chelating dppf and a terminal C(2)N(3) unit, giving three-legged piano-stool geometry. The C-N-C angle of the N(CN)(2) ligand [120.8?(6)°] is significantly smaller than that in the corresponding diruthenium complex [127.2?(9)°; Zhang et al. (2003 ?). Inorg. Chem.42, 633-640] due to steric hindrance between the two {Cp(PPh(3))(2)Ru} building blocks. Disorder was found in the dichloro-methane solvent mol-ecule, which was refined as disordered over two positions, with a site-occupancy ratio of 0.53:0.47?(2).
