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

ABSTRACT: 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)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)-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-thio-phosphino-yl)-4-ethyl-aniline.

Project description:The title compound, C32H29NP2S2, has two mol-ecules in the asymmetric unit, with an r.m.s. difference of 0.218 Å in their best-fit overlay. Both mol-ecules have a slightly distorted trigonal-planar N atom, bonded to two P(V) atoms and a C atom of the 4-ethyl-phenyl unit. The P-N-P angles of 126.34 (11) and 125.98 (11)° are larger than the four C-N-P bond angles. The two S atoms are trans to one another with respect to the P-N-P angle. The crystal structure features C-H⋯π inter-actions. The methyl group in one of the mol-ecules is disordered over two sets of sites, with occupancies of 0.518 (6) and 0.482 (6).

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

Project description: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.

[?-1,2-Bis(diphenyl-phosphino)ethane-?P:P']bis-{[1,2-bis-(diphenyl-phosphino)ethane-?P,P']cyanidocopper(I)} methanol disolvate.

Project description:The title centrosymmetric complex, [Cu(2)(CN)(2)(C(26)H(24)P(2))(3)]·2CH(3)OH, consists of two five-membered [Cu(dppe)CN] rings [dppe is 1,2-bis-(diphenyl-phosphino)ethane] bridged by one ?(2)-dppe ligand, and two methanol solvent mol-ecules. The angles around the central metal atom indicate that each Cu(I) atom is located in the center of a distorted tetra-hedron. The coordination sphere of each Cu(I) atom is formed by three P atoms from two dppe ligands, and one C atom from the cyanide ligand. The crystal structure is stabilized by O-H?N hydrogen bonds, which are formed by the O-H donor group from methanol and the N-atom acceptor from a cyanide ligand.

4,6-Bis(diphenyl-phosphino)phenoxazine (nixantphos).

Project description:The title compound, C(36)H(27)NOP(2), has been reported as a ligand on rhodium for the catalysis of hydro-formyl-ation reactions. The key feature of the compound is the intra-molecular P⋯P distance of 4.255 (2) Å. The bond angles at the P atoms range from 99.93 (10) to 103.02 (10)°. The phenoxazine ring system is essentially planar and a non-crystallographic mirror plane through the N⋯O vector bis-ects the mol-ecule. The C-O bond lengths range from 1.388 (2) to 1.392 (2) Å and the C-N bond lengths range from 1.398 (3) to 1.403 (3) Å.

[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.

Bis{1-[2-(diphenyl-phosphino)-ethyl]-3-ethylimidazol-2-yl-idene}palladium(II) bis-(hexa-fluoridophosphate) acetonitrile 2.85-solvate.

Project description:In the structure of the title compound, [Pd(C(19)H(21)N(2)P)(2)](PF(6))(2)·2.85CH(3)CN, the two six-membered NHC-phosphane chelate rings form a distorted square-planar coordination geometry around the Pd(II) atom, which lies 0.212?(1)?Å above the coordination plane. The sum of the bond angles at Pd(II) is 358.3°, with C-Pd-P bite angles of 84.03?(10) and 83.54?(9)°. The structure includes three acetonitrile solvent mol-ecules, one with partial site occupation and one with severe disorder, which was eventually excluded from the refinement.

[?-1,1'-Bis(diphenyl-phosphino)ferrocene]bis-{[(Z)-O-ethyl N-phenyl-thio-carbamato-?S]gold(I)} dichloro-methane solvate.

Project description:The binuclear title compound, [Au(2)Fe(C(9)H(10)NOS)(2)(C(17)H(14)P)(2)]·CH(2)Cl(2), which has the Fe atom located on a crystallographic centre of inversion, crystallizes as a 1:1 dichloro-methane solvate, which is disordered about a centre of inversion. There is a small deviation from linearity defined by the SP donor set [S1-Au-P1 angle is 175.35?(5) °] which is due to an intra-molecular Au?O contact [3.080?(5)?Å]. The primary inter-molecular contacts between binuclear mol-ecules are of the type C-H??, and are arranged so as to form columns in the a-axis direction in which the disordered solvent mol-ecules reside.
