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-?²P,P']platinum(II) bis-(trifluoro-methane-sulfonate).

Project description:The title compound, [Pt(C??H??NP?)?](CF?SO?)?, 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 ? = 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.

?-Bis(diphenyl-phosphan-yl)borato-?P:P'-bis-[dicarbon-yl(?-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)°].

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.

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.

[1,2-Bis(dimethyl-phosphino)ethane]carbon-yl(?-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.

[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.

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.
