Poly[di-?(3)-chlorido-di-?(2)-chlorido-{?(4)-N,N,N',N'-tetra-kis-[(diphenyl-phosphan-yl)meth-yl]benzene-1,4-diamine-?(4)P:P':P'':P'''}tetra-copper(II)].

ABSTRACT: In the title complex, [Cu(4)Cl(4)(C(58)H(52)N(2)P(4))](n), four Cu(II) atoms are held together via two doubly bridging and two triply bridging chlorides, forming a stair-like Cu(4)Cl(4) core having crystallographically imposed inversion symmetry, while the benzene-1,4-diamine ligand (with a crystallographic inversion center at the centroid) acts in a tetra-dentate coordination mode, bridging two adjacent Cu(4)Cl(4) cores, resulting in a chain along the a-axis direction. One Cu atom has a distorted tetra-hedral geometry, coordinated by one P atom, one ?(2)-Cl and two ?(3)-Cl atoms, while the second Cu atom adopts a trigonal geometry, coordinated by one P atom, one ?(2)-Cl and one ?(3)-Cl atoms.

Project description:In the title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(58)H(52)N(2)P(4))](BF(4))(2), the dinuclear cation lies on an inversion centre. The Cu(I) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and two P atoms from an N,N,N',N'-tetra-kis-[(diphenyl-phos-phan-yl)meth-yl]benzene-1,4-diamine ligand in a distorted tetra-hedral geometry. In the crystal, inter-molecular C-H?F hydrogen bonds link the ions into layers parallel to [[Formula: see text]01]. ?-? inter-actions [centroid-centroid distance = 3.668?(4)?Å] are also observed. One F atom of the anion is disordered over two orientations with a refined occupancy ratio of 0.675?(13):0.325?(13).

[μ-N,N,N',N'-Tetra-kis(diphenyl-phosphino-meth-yl)benzene-1,4-diamine-κP,P':P'',P''']bis-[bis-(nitrato-κO)palladium(II)].

Project description:The asymmetric unit of the title complex, [Pd(2)(NO(3))(4)(C(58)H(52)N(2)P(4))], contains one half-mol-ecule, in which the central benzene ring is located on a crystallographic centre of inversion. The Pd atom has a distorted square-planar coordination consisting of two P and two O atoms. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains, and π-π contacts between the phenyl rings [centroid-centroid distance = 3.928 (3) Å] may further stabilize the structure.

Poly[[diaqua-tetra-kis-(μ(2)-benzene-1,4-di-carbonitrile-κN:N')iron(II)] bis-[tetra-chlorido-ferrate(III)] nitro-methane tetra-solvate].

Project description:In the title compound, {[Fe(II)(C(8)H(4)N(2))(2)(H(2)O)(2)][Fe(III)Cl(4)](2)·4CH(3)NO(2)}(n), the Fe(II) and Fe(III) ions are hexa- and tetra-coordinated, respectively. Each unique benzene-1,4-dicarbonitrile mol-ecule lies across a crystallographic inversion centre and bridges two Fe(II) ions (each situated on an inversion centre), generating two-dimensional (4,4) square grid layers. The tetra-chloridoferrate(III) anions and nitro-methane solvent mol-ecules lie between the square grid layers and are further link to the adjacent layers into a three-dimensional supra-molecular structure through O-H⋯Cl and O-H⋯O hydrogen bonds.

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.

Chlorido{N,N-dibenzyl-N,N-bis-[(diphenyl-phosphan-yl)meth-yl]pyridine-2,6-diamine}-methyl-platinum(II).

Project description:In the title mononuclear complex, [Pt(CH(3))Cl(C(45)H(41)N(3)P(2))], the pyridine-2,6-diamine ligand can be viewed as a centrosymmetric motif having two pendant N-benzyl-N-[(diphenyl-phosphan-yl)meth-yl] arms, the two P atoms of which chelate to the Pt(II) ion, forming a ten-membered metallocycle. A distorted square-planar coordination geometry around the Pt(II) atom is completed by a methyl ligand and a chloride ion. The packing between the mononuclear units is achieved through C-H⋯π inter-actions, which link the mol-ecules into chains along the c axis.

Project description:In the centrosymmetric dinuclear title compound, [Cu(2)(C(2)H(3)N)(2)(C(18)H(10)N(4))(2)(C(32)H(30)N(2)P(2))](BF(4))(2), the Cu(I) centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N'-bis-[(diphenyl-phosphan-yl)meth-yl]benzene-1,4-diamine (bpbda) ligand, and one N atom from an acetonitrile mol-ecule in a distorted tetra-hedral geometry. The bpbda ligand, lying on an inversion center, bridges two Cu(I) centres into a Z-shaped complex. Intra-molecular ?-? inter-actions between the dipyridophenazine ligand and the benzene ring of the bpbda ligand are observed [centroid-centroid distance = 3.459?(3)?Å]. The crystal structure also involves inter-molecular ?-? inter-actions between the dipyridophenazine ligands [centroid-centroid distance = 3.506?(3)?Å], which lead to a one-dimensional supra-molecular structure.

Crystal structure of di-chlorido-[2-(di-phenyl-phosphan-yl)-3,4,5,6-tetra-fluoro-benzene-1-thiol-ato-κ(2) P,S]gold(III).

Project description:The title compound, [Au(C18H10F4PS)Cl2], crystallizes as neutral mol-ecules, with the Au(III) atom coordinated by two Cl atoms and by the P and S atoms of the bidentate phosphanyl thiol-ate ligand, in a slightly distorted square-planar environment. The mol-ecules are linked into centrosymmetric dimers via long axial Au-Cl bonds of 3.393 (4) Å. This axial Au-Cl distance is longer than is usually seen, although one other example has been given. Dimer formation may explain the unexpectedly low solubility of the compound in common polar solvents. There is also a separate inter-molecular Au-F contact of 3.561 (6) Å, but this distance seems too long to be regarded as a bond. Two putative C-H⋯F hydrogen bonds appear to link the dimers into sheets parallel to (110). There is a short inter-molecular F⋯F contact of 2.695 (10) Å between two dimers related by the twofold axis.

N,N-Diethynyl-N,N-diphenyl-benzene-1,4-diamine.

Project description:The title compound, C(22)H(16)N(2), is the first example of an ynamine with H atoms bonded to the terminal C atoms. The environment around each N atom is almost planar. The distances of the N atoms from a least squares plane fitted through each N atom and the surrounding three C atoms, are 0.087 (3) and 0.041 (4) Å. The dihedral angles between these two planes and the central phenyl-ene ring are 23.34 (14) and 34.57 (14)°. The two acetyl-ene groups have an anti conformation, keeping a conjugation through the central benzene ring. The freely refined lengths of C(sp)-H are 1.00 (5) and 0.93 (4) Å, consistent with those of reported acetyl-enes. The H atoms bound to terminal C atoms have short contacts with the neighboring acetyl-enic C and N atoms. The closest contacts are an H⋯N distance of 2.67 (5) Å and an H⋯C distance of 2.74 (5) Å.

The Ru(II) atom has a typical piano-stool coordination, defined by the indenyl ligand, one Cl atom and two phosphanyl P atoms. The Ru-P bond lengths are 2.2502?(9) and 2.2968?(8)?Å.
