Bis(?-2-hy-droxy-methyl-2-methyl-propane-1,3-diolato)bis-[di-chlorido-titanium(IV)] diethyl ether disolvate.

ABSTRACT: The title complex, [Ti2Cl4{CH3C(CH2O)2(CH2OH)}2], lies across a centre of symmetry with a diethyl ether solvent mol-ecule hydrogen bonded to the -CH2OH groups on either side of it. The Ti(IV) atom is coordinated in a distorted octa-hedral geometry by a tripodal ligand and two terminal chloride atoms. There are three coordination modes for the tripodal ligand distinguishable on the basis of their very different Ti-O bond lengths. For the terminal alkoxo ligand, the Ti-O distance is 1.760?(1)?Å, the asymmetric bridge system has Ti-O bond lengths of 1.911?(1) and 2.048?(1)?Å. The Ti-O bond length for the alcohol O atom is the longest at 2.148?(1)?Å.

Poly[[bis-(?-4,4'-bipyridyl-?N:N')bis-(thio-cyanato-?N)manganese(II)] diethyl ether disolvate].

Project description:In the title compound, {[Mn(NCS)(2)(C(10)H(8)N(2))(2)]·2C(4)H(10)O}(n), the Mn(II) ion is coordinated by four N-bonded 4,4'-bipyridine (bipy) ligands and two N-bonded thio-cyanate anions in a distorted octa-hedral coordination geometry. The asymmetric unit consists of one Mn(II) ion and two bipy ligands each located on a twofold rotation axis, as well as one thio-cyanate anion and one diethyl ether mol-ecule in general positions. In the crystal structure, the metal centers with terminally bonded thicyanate anions are bridged by the bipy ligands into layers parallel to (001). The diethyl ether solvent mol-ecules occupy the voids of the structure.

[6,6'-Bis(1,1-di-methyl-eth-yl)-4,4'-dimethyl-2,2'-methyl-enediphenolato-?(2) O,O']di-chlorido-(9H-fluoren-9-ol-?O)titanium(IV)-fluorene-diethyl ether (1/0.5/1).

Project description:The title adduct, [TiCl2(C23H30O2)(C13H10O]·0.5C13H10·C4H10O, is a monomer with a trigonal-bypyramidal coordination sphere of the Ti(IV) atom in which the ligand O atoms of the bidentate diphenolate anion are located in both apical and equatorial positions. Chloride ligands occupy the remaining two equatorial sites of the trigonal bypyramid with the fluoren-9-ol O atom occupying the other apical site. The hy-droxy group H atom of this latter group is hydrogen bonded to an O atom of a non-coordinating diethyl ether mol-ecule. The title compound also contains a further fluorene solvent mol-ecule, which lies across a centre of symmetry and which is equally disordered over an inversion centre.

Bis[?-1,3-bis-(di-phenyl-phosphan-yl)propane-?(2) P:P']digold(I) tetra-chloridonickelate(II) diethyl ether monosolvate.

Project description:The title compound, [Au2(C27H26P2)2][NiCl4]·C4H10O, consists of a digold(I) complex cation, an [NiCl4](2-) complex anion and a diethyl ether solvent mol-ecule. Two 1,3-bis-(di-phenyl-phosphan-yl)propane (dppp) ligands bridge two Au(I) atoms, forming a metallacycle in which each of the Au(I) atoms is coordinated in a slightly distorted linear environment by two P atoms. In the complex anion, the Ni(II) atom is coordinated by four chloride ligands in a distorted tetra-hedral geometry. The complex cation and the complex anion form a cation-anion pair through two Au?Cl contacts of 3.040?(1) and 3.021?(2)?Å. One of the phenyl groups of the dppp ligand is disordered over two positions with equal occupancies.

Crystal structure of bis-(bis-{?<sub>3</sub>-3-methyl-3-[(4-nitro-2-oxido-benzyl-idene)amino]-propane-1,3-diolato}tris-[chlorido-(dimethyl sulfoxide)-iron(III)]) dimethyl sulfoxide hepta-solvate dihydrate.

Project description:The title compound, [Fe3(C11H11N2O5)2Cl3(C2H6OS)3]2·7C2H6OS·2H2O, was isolated accidentally from an Fe0-NiCl2·6H2O-H3L-TEA-DMSO system [where H3L is the product of the condensation between p-nitro-salicyl-aldehyde and 2-amino-2-methyl-propane-1,3-diol and dimethyl sulfoxide (DMSO), and TEA is triethylamine]. The structure is based on a trinuclear {Fe3(?-O)4} core, with an angular arrangement of the FeIII ions that can be explained by the geometrical restrictions of two bulky ligands, each coordinating to all of the metal cations.

Bis[bis-(penta-methyl-cyclo-penta-dien-yl)cobalt(III)] tetra-chlorido-cobaltate(II) di-chloro-methane disolvate.

Project description:The title compound, [Co(C10H15)2]2[CoCl4]·2CH2Cl2, was isolated as a dichloromethane solvate and was formed in the reaction between lithium penta-methyl-cyclo-penta-dienide and anyhydrous cobalt(II) chloride in tetra-hydro-furan. There are two deca-methyl-cobaltocenium cations, one tetrachloridocobaltate(II) anion and two di-chloro-methane solvent mol-ecules in the formula unit. There is a slight disorder of the di-chloro-methane solvent which was treated with a two-site model [occupancy rates = 0.765?(4) and 0.235?(4)]. The di-chloro-methane mol-ecules display significant C-H?Cl inter-actions with the tetrachloridocobaltate(II) dianion. The cobalt atom of the deca-methyl-cobaltocenium cation sits on a twofold rotation axis, with only one penta-methyl-cyclo-penta-diene ligand being unique and the second generated by symmetry. The cobalt atom of the [CoCl4](-2) ion sits on a special site with -4 symmetry, with one unique chloride ligand and the others generated by the fourfold inversion axis.

8-Hy-droxy-2-methyl-quinolinium tetra-chlorido(quinolin-2-olato-?N,O)stannate(IV) methanol disolvate.

Project description:In the reaction of 8-hy-droxy-quinoline, 2-methyl-8-hy-droxy-quinoline and stannic chloride, the 2-methyl-8-hy-droxy-quinoline is protonated, yielding the disolvated title salt, (C(10)H(10)NO)[SnCl(4)(C(9)H(6)NO)]·2CH(3)OH. The Sn(IV) atom in the anion is N,O-chelated by the hy-droxy-quinolinate in a cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation, anion and solvent mol-ecules are linked by N-H?O, O-H?O and O-H?Cl hydrogen bonds, generating a three-dimensional network.
