Diacetonitrile[N,N'-bis(2,6-diisopropyl-phenyl)ethane-1,2-diimine]dichloridochromium(II) acetonitrile solvate.

ABSTRACT: The title compound, [CrCl(2)(CH(3)CN)(2)(C(26)H(36)N(2))]·CH(3)CN, was synthesized by the reaction of CrCl(2)(THF)(2) with N,N'-bis-(2,6-diisopropyl-phen-yl)ethane-1,2-diimine in dichloro-methane/acetonitrile. The chromium center is coordinated by two N atoms of the chelating diimine ligand, two chloride ions in a trans configuration with respect to each other, and by two N atoms of two acetonitrile mol-ecules in a distorted octa-hedral geometry.

Project description:In the mol-ecular structure of the title compound, [Cr(2)Cl(4)(C(26)H(36)N(2))(2)(C(4)H(8)O)]·4.5CH(2)Cl(2), the two Cr(II) centers are bridged by three Cl atoms, forming a dinuclear complex. Each Cr(II) center is coordinated by one chelating bis-(2,6-diisopropyl-phen-yl)ethane-1,2-diimine ligand via both N atoms. An additional chloride ion binds to one chromium center, whereas an additional tetra-hydro-furan mol-ecule coordinates to the second Cr(II) center. The coordination geometry at each Cr(II) center can be best described as distorted octa-hedral.

N,N'-Bis[3,5-bis-(2,6-diisopropyl-phen-yl)phen-yl]butane-2,3-diimine.

Project description:The title mol-ecule, C(64)H(80)N(2), lies on an inversion center wherein the central butane-diimine fragment [N=C(Me)-C(Me)=N] is essentially planar [maximum deviation = 0.002 (2) Å] and its mean plane forms a dihedral of 70.88 (10)° with the attached benzene ring. In the symmetry-unique part of the mol-ecule, the dihedral angles between the benzene ring bonded to the N atom and the other two benzene rings are 89.61 (6) and 82.77 (6)°.

Bis[?-1,2-diphenyl-N,N'-bis-(di-2-pyridyl-methyl-eneamino)ethane-1,2-diimine]disilver(I) bis-(hexa-fluorido-phosphate) acetonitrile disolvate.

Project description:In the centrosymmetric dinuclear title compound, [Ag(2)(C(36)H(26)N(8))(2)](PF(6))(2)·2C(2)H(3)N, the Ag(+) ion is bound to four N atoms from two 1,2-diphenyl-N,N'-bis-(di-2-pyridyl-methyl-eneamino)ethane-1,2-diimine ligands in a distorted tetra-hedral geometry. The ligand adopts a twist conformation, coordinating two metal centers by three pyridyl N atoms and one imine N atom and spanning two Ag(+) ions, resulting in the formation of a helical dimeric structure.

1,2-Bis(phenyl-phosphor-yl)ethane.

Project description:The geometric parameters of the mol-ecule of the title compound, C(14)H(16)O(2)P(2), are in the usual ranges. It is a meso compound with the two chiral P atoms having opposite configurations. The P-CH(2)-CH(2)-P chain adopts a trans conformation [torsion angle -178.59 (17)°]. The P=O bonds are almost coplanar with the adjacent phenyl ring [torsion angles = 3.8 (3) and 0.3 (3)°]. Whereas one of them is synclinal [torsion angle = -59.0 (2)°] to the central C-C bond, the other is anti-clinal [torsion angle = 56.6 (2)°] to the central C-C bond. The dihedral angle between the two phenyl rings is 5.2 (3)°. The mol-ecules are linked by weak C-H⋯O hydrogen bonds. They crystallize in rows running along the c axis.

(Ethane-1,2-di-yl)bis-[bis-(3-methoxy-prop-yl)methyl-phospho-nium] bis-(tetra-phenyl-borate) diethyl ether solvate.

Project description:In the course of substitution studies on the iron dihydrogen complex trans-[Fe(DMeOPrPE)(2)(H(2))H](BPh(4)) {DMeOPrPE = 1,2-bis-[bis-(methoxy-prop-yl)phosphino]ethane}, we discovered an unexpected transformation of the diphosphine ligand to a diphospho-nium dication without the use of any typical methyl-ating reagent. The P atoms in the dication of the title compound, C(20)H(46)O(4)P(2) (2+)·2C(24)H(20)B(-)·C(4)H(10)O, have a distorted tetra-hedral coordination with P-C(Me) distances of 1.791?(2) and 1.785?(2)?Å. The P-C-C-P torsion angle about the central dimethyl-ene bridge is -168.3?(1)°.

Project description:The cation of the title salt, C(34)H(45)N(2) (+)·PF(6) (-), is a protonated form of an unsymmetrical overcrowded β-imino-amine. The observed bond lengths [C-N = 1.326 (4)-1.341 (4) Å and C-C = 1.383 (4)-1.391 (4) Å] suggest significant delocalization within the π system of the N C C C N backbone.

Bis(N-phenyl-ethane-1,2-diamine)dithio-cyanato-nickel(II).

Project description:The asymmetric unit of the title mononuclear Ni(II) compound, [Ni(NCS)(2)(C(8)H(12)N(2))(2)], contains two independent half-mol-ecules, the Ni atoms of which lie on crystallographic inversion centres. Each Ni(II) ion is chelated by two N atoms from two N-phenyl-ethane-1,2-diamine ligands and is also coordinated by two N atoms from two thio-cyanate ligands, giving a distorted octa-hedral geometry. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (100) by N-H?S inter-actions.
