Catena-Poly[[(tetra-hydro-furan-?O)lithium(I)]-bis-(?-trimethyl-silanolato-?O:O)-gallium(III)-bis-(?-trimethyl-silanolato-?O:O)-[(tetra-hydro-furan-?O)lithium(I)]-?-bromido].

ABSTRACT: 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).

Tetra-kis(μ-penta-fluoro-benzoato-κO:O')bis-[(tetra-hydro-furan-κO)molybdenum(II)].

Project description:In the asymmetric unit of the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(4)H(8)O)(2)], two independent half-mol-ecules are present, which are completed by a crystallographically imposed center of inversion between the individual Mo atoms. In each mol-ecule, four penta-fluoro-benzoate anions bridge the quadruply bonded Mo(2) (4+) unit that is, in addition, axially coordinated by two O atoms of tetra-hydro-furan (THF) mol-ecules. In the two independent mol-ecules, the mean Mo-Mo bond length is 2.110 Å. Since the THF mol-ecules are equally disordered over two sets of sites, there are four different Mo-O distances in both half-mol-ecules with an overall mean of 2.542 Å. A zigzag chain is formed by π-π stacking inter-actions between penta-fluoro-phenyl rings, indicated by a centroid-centroid distance of 3.7054 (11) Å and a centroid-to-plane distance of 3.4169 (3) Å. The extension of the unit gives a three-dimensional network structure with the THF mol-ecules located in the voids.

Bis(nona-fluoro-butane-sulfonato-κO)dioxidotris(tetra-hydro-furan-κO)uranium(VI).

Project description:In the title compound, [U(C(4)F(9)O(3)S)O(2)(C(4)H(8)O)(3)], each U(VI) ion is located on a twofold rotation axis and is seven-coordinated by two terminal O atoms in the axial positions [U-O = 1.737 (5) Å] and five O atoms from two monodentate nona-fluoro-butane-sulfonate (NfO(-)) and three tetra-hydro-furan ligands in the equatorial plane [U-O = 2.388 (5)-2.411 (4) Å] in a penta-gonal-bipyramidal geometry. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds involving the non-coordinated O atoms of the NfO(-) ligands.

Bis[μ(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.

catena-Poly[[tetra-kis(μ(2)-acetato-κO:O')dicopper(II)(Cu-Cu)]-μ(2)-acetato-κO:O'-[bis-[μ(2)-3-(dimethyl-amino)propan-1-olato]-κN,O:O;κO:N,O-bis-[(tetra-hydro-furan-κO)copper(II)]]-μ(2)-acetato-κO:O'].

Project description:The title complex, [Cu(4)(C(5)H(12)NO)(2)(C(2)H(3)O(2))(6)(C(4)H(8)O)(2)](n), consists of dinuclear [Cu(2)(C(5)H(12)NO)(2)(THF)(2)] (THF is tetra-hydro-furan) and [Cu(2)(CH(3)COO)(4)] units linked through acetate ions, generating parallel one-dimensional polymeric chains propagating in the [10] direction. In the first dinuclear unit, Cu(II) ions related by inversion symmetry are bridged by two 3-(dimethyl-amino)propan-1-olate ligands. Likewise, a pair of inversion-related Cu(II) ions are bridged by four acetate groups. The crystallographically independent Cu centers are linked to one another by a single bridging acetate group, generating an infinite chain. The distorted square-pyramidal coordination of the first metal center is completed with an apical THF mol-ecule, with a long Cu-O bond length of 2.476 (5) Å. The geometry around the other metal atom is close to octa-hedral, and the Cu⋯Cu separation in this unit is 2.652 (1) Å. The distance between the metal centers in the first dinuclear unit is considerably longer [3.068 (1) Å], suggesting little or no bonding inter-action. The Cu⋯Cu separation between two acetate-bridged independent Cu centers is 4.860 (2) Å. The THF mol-ecule has methyl-ene groups disordered over two positions, with occupancies of 0.608 (13) and 0.392 (13).

Crystal structure of tetra-kis-(tetra-hydro-furan-κO)bis-(tri-fluoro-methane-sulfonato-κO)iron(II).

Project description:The title compound, [Fe(CF3SO3)2(C4H8O)4], is octa-hedral with two tri-fluoro-methane-sulfonate ligands in trans positions and four tetra-hydro-furane mol-ecules in the equatorial plane. By the conformation of the ligands the complex is chiral in the crystal packing. The compound crystallizes in the Sohncke space group P212121 and is enanti-omerically pure. The packing of the mol-ecules is determined by weak C-H⋯O hydrogen bonds. The crystal studied was refined as a two-component inversion twin.

Crystal structure of tri-benzyl-bis-(tetra-hydro-furan-κO)lutetium(III).

Project description:In the title compound, [Lu(C7H7)3(C4H8O)2] (1), the Lu ion is coordinated by three benzyl and two tetra-hydro-furan ligands. Two of the benzyl groups are bonded in a classical η1-fashion through the methyl-ene via the ipso-carbon atom of the benzyl ligand in addition to bonding through the methyl-ene C atom, resulting in a modified trigonal-bipyramidal coordination geometry about the Lu center.

Di-μ-bromido-tris-(triphenyl-phosphine)-1κP,2κP-disilver(I) tetra-hydro-furan 0.85-solvate.

Project description:In the title binuclear silver(I) complex, [Ag(2)Br(2)(C(18)H(15)P)(3)]·0.85C(4)H(8)O, the two independent silver(I) ions are briged by two bromide ions. One Ag(I) ion is coordinated by two triphenyl-phosphine groups with a square-planar geometry, while the second is coordinated by one triphenyl-phine group with a trigonal-planar geometry. The structure is very similar to that of the dichloro-methane solvate reported by Zhu, Huang & Zheng [Chin. J. Struct. Chem. (1994), 13, 325-327]. The tetrahydrofuran solvent molecule is disordered and was refined with a fixed occupancy of 0.85.

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.

Tris[μ-2,2'-(azinodimethylidyne)diphenolato-κO,N:N',O']diiron(III) tetra-hydro-furan tetra-solvate.

Project description:In the title binuclear iron(III) complex, [Fe(2)(C(14)H(10)N(2)O(2))(3)]·4C(4)H(8)O or [Fe(2)(salda)(3)]·4THF [H(2)salda = 2,2'-(azinidimethyl-ene)diphenolate and THF is tetra-hydro-furan], the ligand possesses a rotationally flexible single N-N bond. Three dinucleating O,N:N',O'-donor ligands provide three diazine (=N-N=) bridges between the metal ions, yielding a binuclear triple helicate structure with crystallographic C(2) symmetry, the rotation axis bis-ecting one N-N bond.

[μ(2)-Bis(diphenyl-phosphanyl)methane][μ(3)-bis-(diphenyl-phosphanyl)meth-yl]trichlorido-tetra-gold(I) tetra-hydro-furan disolvate.

Project description:The title tetra-nuclear complex, [Au(4)(C(25)H(21)P(2))Cl(3)(C(25)H(22)P(2))]·2C(4)H(8)O, features two non-equivalent Ph(2)PCPPh(2) fragments, one of which represents the 'complete' mol-ecule (with two H atoms at the central C atom); each of the two P atoms of this mol-ecule is coordinated by an Au atom [Au-P = 2.2256 (13) and 2.2710 (13) Å], and these two Au atoms form an Au-Au bond [3.2945 (3) Å], thus closing the five-membered Au(2)P(2)C ring. The first of these Au atoms has a terminal chlorido ligand [Au-Cl = 2.2806 (12) Å], whereas the second Au atom forms a covalent bond with the central C atom of the bis-(diphenyl-phosphino)methyl group [Au-C = 2.114 (5) Å]; the latter group in turn coordinates with its P atoms the gold atoms of the Cl-Au-Au-Cl group [Au-P = 2.2356 (13) and 2.2338 (13), Au-Au = 3.3177 (3), Au-Cl = 2.3091 (12) and 2.2950 (13) Å], thus closing the second Au(2)P(2)C ring. The two such rings have different chemical functions, but both exhibit envelope conformations. However, the first (with different substituents at the Au atoms) is non-symmetrical with one of the P atoms in the flap position of the envelope; the other one has a conformation with mirror symmetry, and the gold-substituted C atom is displaced by 0.740 (5) Å from the almost exactly planar (r.m.s. deviation = 0.0038 Å) Au(2)P(2) group.
