Di-?-chlorido-bis-{[N,N'-dicyclo-hexyl-N'',N''-bis-(trimethyl-sil-yl)guanidinato-?N,N'](tetra-hydro-furan-?O)magnesium(II)}.

ABSTRACT: The dinuclear title complex, [Mg(2)(C(19)H(40)N(3)Si(2))(2)Cl(2)(C(4)H(8)O)(2)], lies on a center of inversion. The Mg(2+) ions are bonded to a chelating N,N'-bonded guanidinate anion, a tetra-hydro-furan mol-ecule and two bridging chloride anions. The geometry of the resulting five-coordinated Mg(2+) ion is a very distorted square-based pyramid with the O atom in the apical position.

Project description:In the title monomeric rare earth complex, [LiNd(C(19)H(40)N(3)Si(2))(2)Cl(2)(C(4)H(8)O)(2)], the [(Me(3)Si)(2)NC(NCy)(2)](2)Nd(+) (Me is methyl, Cy is cyclo-hex-yl) and Li(THF)(2) (+) units (THF is tetra-hydro-furan) are connected by two bridging Cl atoms. The Nd(3+) ion is coordinated by two guanidinate ligands and two Cl atoms, forming a distorted chelating octa-hedral geometry. The Li(+) ion is four-coordinated by two Cl atoms and two O atoms from THF mol-ecules in a distorted tetra-hedral geometry.

Bis[?(2)-1,1-(butane-1,4-di-yl)-2,3-dicyclo-hexyl-guanidinato]bis-[(tetra-hydro-furan)-lithium](Li-Li).

Project description:In the dinuclear centrosymmetric title complex, [Li(2)(C(17)H(30)N(3))(2)(C(4)H(8)O)(2)], the Li(+) cation is coordinated by three N atoms from two guanidinate ligands and an O atom from tetra-hydro-furan (THF) in a strongly distorted tetrahedral environment. In the guanidinate-bridged THF-stabilized dimer the Li?Li separation is short at 2.479?(8)?Å.

Dicyclo-hexyl-ammonium trimethyl-bis-(hydrogen phenyl-phospho-nato)stannate(IV).

Project description:In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H?O hydrogen bonds involving the hy-droxy group of the hydrogen phenyl-phospho-nate ion. The chains inter-act with one another via O-H?O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclo-hexyl-ammonium ion through N-H?O hydrogen bonds, forming a three-dimensional network.

Project description:The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57?(2) and 0.43?(2).

Bis(dicyclo-hexyl-phenyl-phosphine)silver(I) nitrate.

Project description:The title compound, [Ag(C(18)H(27)P)(2)]NO(3), is a mononuclear salt species in which the Ag atom is coordinated by two phosphine ligands, forming a cation, with the nitrate as the counter-anion, weakly inter-acting with the Ag atom, resulting in Ag?O distances of 2.602?(6) and 2.679?(6)?Å. The cationic silver-phosphine complex has a non-linear geometry in which the P-Ag-P angle is 154.662?(19)°. The Ag-P bond lengths are 2.4303?(6) and 2.4046?(5)?Å.

[1,1'-Bis(dicyclo-hexyl-phosphino)cobalto-cenium-?P,P']chlorido(?-cyclo-penta-dien-yl)ruthenium(II) hexa-fluorido-phosphate.

Project description:In the title structure, [CoRu(C(5)H(5))(C(17)H(26)P)(2)Cl]PF(6), the Ru(II) atom is bonded to a cyclo-penta-dienyl ring, a Cl atom and two P atoms of the chelating 1,1'-bis-(dicyclo-hexyl-phosphino)cobaltocenium (di-cypc) ligand, leading to a three-legged piano-stool coordination. Part of the PF(6) (-) counter-anion is disordered over two positions, with a site-occupancy ratio of 0.898?(7):0.102?(7). The components are linked by C-H?F and C-H?Cl hydrogen bonds.

Dicyclo-hexyl-ammonium bis-(chloro-difluoro-acetato-?O)cyclo-hexyl-diphenyl-stannate(IV).

Project description:In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the hydrogen-bonding inter-actions giving rise to linear hydrogen-bonded chains.

2,3,5,6-Tetra-fluoro-1,4-bis-(trimethyl-sil-yl)benzene.

Project description:The asymmetric unit of the title compound, C(12)H(18)F(4)Si(2), contains two independent mol-ecules, both lying on inversion centers. The C(arene)-Si distances are significantly longer than in the analogous non-fluorinated compound. The packing of the mol-ecules results in a herringbone motif in the ac plane.
