[N,N-Bis(diphenyl-phosphino)propyl-amine-?P,P']dichloridoplatinum(II).

ABSTRACT: The Pt(II) atom in the title compound, [PtCl(2)(C(27)H(27)NP(2))], has a highly distorted square-planar geometry, as evidenced by the P-Pt-P bite angle [72.4?(1)°]. The strain in the complex is further illustrated by the distorted tetra-hedral angles of the P atoms, which range between 93.5?(1) and 122.2?(1)°. It is of inter-est to note that the N atom has to adopt an almost planar geometry with the two P atoms and the C atom attached to it [it is displaced by 0.093?(2)?Å from the CP(2) plane] in order to accommodate the steric bulk of the phenyl groups and the alkyl group of the ligand coordinated to the Pt(II) centre. The mol-ecules pack in horizontal rows across the bc plane. C-H?Cl hydrogen bonds stabilize the crystal packing.

N,N-Bis(diphenyl-phosphino)-1,2-dimethyl-propyl-amine.

Project description:The diphenyl-phosphine groups in the title compound, C(29)H(31)NP(2), are staggered relative to the PNP backbone. The N atom adopts an almost planar geometry with the two P atoms and the C atom attached to it, in order to accommodate the steric bulk of the phenyl groups and the alkyl group. Three C atoms of the 1,2-dimethylpropylamine group are disordered over two positions in a 9:1 ratio. The mol-ecules pack diagonally in the unit cell across the ac plane in a head-to-tail fashion.

[N,N-Bis(diphenyl-phosphino)isopropyl-amine]dibromidonickel(II).

Project description:The title compound, [NiBr(2)(C(27)H(27)NP(2))], was synthesized by the reaction of NiBr(2)(dme) (dme is 1,2-dimethoxy-ethane) with N,N-bis-(diphenyl-phosphino)isopropyl-amine in methanol/tetra-hydro-furan. The nickel(II) center is coordinated by two P atoms of the chelating PNP ligand, Ph(2)PN(iPr)PPh(2), and two bromide ions in a distorted square-planar geometry.

N,N-Bis(diphenyl-phosphino)ethyl-amine.

Project description:In the title compound, C(26)H(25)NP(2), the diphenyl-phosphino groups are staggered relative to the PNP backbone, even though the ethyl substituent coordinated to the N atom is not sterically bulky. The N atom adapts an almost planar geometry with two P atoms and a C atom of the allyl group attached to it in order to accommodate the steric bulk of the phenyl groups and the alkyl group. The distortion of the trigonal-pyramidal geometry of the nitro-gen is further illustrated by the bond angles which range between 114.0?(1) and 123.7?(1)°. There are no classical inter-molecular inter-actions.

[N,N-Bis(diphenyl-phosphino)propyl-amine-?P,P]bromidotricarbonyl-rhenium(I).

Project description:In the title compound, [ReBr(C(27)H(27)NP(2))(CO)(3)], the Re(I) atom is octa-hedrally surrounded by three carbonyl ligands in a facial arrangement, a bromide ligand and the P,P'-bidentate ligand Bis(diphenyl-phosphino)propyl-amine. The compound exhibits substitutional disorder of the bromide ligand and the axial carbonyl ligand, with almost 50% occupancy for both Br amd CO [0.538?(4) and 0.462?(4), respectively]. In addition, the propyl chain on the N atom of the bidentate ligand exhibits a 0.648?(9):0.352?(9) disorder. C-H?O and C-H?Br hydrogen bonding consolidates the crystal packing.

[1,1'-Bis(diphenyl-phosphino)cobalto-cenium-?P,P']dichloridoplatinum(II) hexa-fluorido-phosphate.

Project description:The title bimetallic compound, [PtCl(2){Co(C(17)H(14)P)(2)}]PF(6), was obtained by reaction of 1,1'-bis-(diphenyl-phosphino)cobalto-cenium hexa-fluorido-phosphate with bis-(acetonitrile)di-chloridoplatinum. The Pt(II) ion is four-coordinated in a slightly distorted square-planar environment by two P atoms of the 1,1'-bis-(diphenyl-phosphino)cobaltocenium moiety and two Cl atoms. In the crystal structure, mol-ecules are linked by weak C-H?F and C-H?Cl hydrogen bonds.

trans-Bis(benzyl-diphenyl-phosphane-?P)dichloridoplatinum(II).

Project description:In the mononuclear title compound, trans-[PtCl2(C19H17P)2], the slightly distorted square-planar coordination sphere of the Pt(II) atom is occupied by two benzyl-diphenyl-phosphane ligands and two chloride atoms in a mutually trans geometry. The effective cone angles for the two phosphane ligands are 160 and 169°. C-H?Cl inter-actions generate infinite long chains along [01-1]. Additional C-H?? and ?-? stacking interactions [centroid-centroid distance = 4.2499?(15)?Å and ring slippage = 2.386?Å] are observed.

{1-[1-(3-Carboxy-propanamido)eth-yl]-1',2-bis-(diphenyl-phosphino)ferrocene-κP,P'}dichloridoplatinum(II) dichloro-methane 1.25-solvate.

Project description:The dinuclear title compound, [FePtCl(2)(C(17)H(14)P)(C(23)H(23)NO(3)P)]·1.25CH(2)Cl(2), has a slightly distorted cis-PtCl(2)P(2) square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2)° about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong inter-molecular O-H⋯O bonds resulting in R(2) (2)(8) rings. A weak intra-molecular N-H⋯Cl bond leads to an S(8) motif. The solvent is highly disordered and has not been modelled with discrete atoms.

Project description:The asymmetric unit of the title compound, [PtCl(2)(C(19)H(17)P)(2)](2)·3CH(2)Cl(2), contains two complex mol-ecules and three dichloro-methane solvent mol-ecules, two of which are disordered over various positions. The Pt(II) complexes reveal a slightly distorted square-planar geometry with average Pt-P and Pt-Cl bond lengthss of 2.252?(8) and 2.363?(8)?Å, respectively, and average P-Pt-P and Cl-Pt-Cl angles of 99.17?(8) and 87.1?(7)°, respectively.

[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.
