Di-?-sulfido-bis-{[rac-1,2-bis-(?(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane]-zirconium(IV)} toluene monosolvate.

ABSTRACT: The title dimeric zirconium complex, [Zr(2)(C(20)H(24))(2)S(2)]·C(7)H(8), was obtained from the reaction of (ebthi)Zr(?(2)-Me(3)Si-C(2)-SiMe(3)) [ebthi is rac-1,2-bis-(?(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each Zr(IV) atom is coordinated by the sterically hindered ebthi ligand and two ?-sulfide ligands in a strongly distorted tetra-hedral geometry. The [ZrS](2) unit is almost planar (mean deviation from the best plane of the four atoms = 0.025?Å). A -CH(2)-CH(2)- group in one ebthi ligand was disordered over two sites, with refined occupancy factors of 0.551?(6) and 0.449?(6). The asymmetric unit also contains a toluene solvent mol-ecule.

Project description:Treatment of [Et(4)N](2)[(edt)(2)Mo(2)S(2)(?-S)(2)] (edt = ethane-dithio-l-ate) with two equivalents of Ag(CH(3)CN)(4)ClO(4) in the presence of bis-(diphenyl-phosphino)methane (dppm) ligand gives rise to the title tetra-nuclear cluster, [Ag(2)Mo(2)(C(2)H(4)S(2))(2)S(4)(C(25)H(22)P(2))(2)]·3C(3)H(7)NO. The complex mol-ecule and one of the dimethyl-formamide (DMF) solvent mol-ecules occupy special positions on a mirror plane. The mol-ecular structure of the complex may be visualized as being built of [Mo(2)S(2)(?-S)(2)(edt)(2)](2-) dianions and [Ag(2)(dppm)(2)](2+) dications connected by two Ag-?-S(edt) and two Ag-?(4)-S bonds.

Project description:Facile ligand substitution is observed when the ruthenium chloride complex [Ru(?(5)-C(9)H(7))Cl(dppe)] (dppe is diphenylphosphanyl ethane) is treated with NaN(3) in refluxing ethanol, yielding the title compound, [Ru(?(5)-C(9)H(7))(N(3))(dppe)] or [Ru(C(9)H(7))(N(3))(C(26)H(24)P(2))]. The Ru(II) atom has a typical piano-stool coordination. The Ru-P bond lengths are 2.284?(2) and 2.235?(2)?Å. NMR and MS analyses are in agreement with the structure of the title compound.

[N,N'-Bis(2,6-diisopropyl-phen-yl)methanimidamidato][?-1,4-bis-(tri-methyl-sil-yl)cyclo-octa-tetra-enyl](tetra-hydro-furan)-samarium(III) toluene monosolvate.

Project description:The title compound, [Sm(C(25)H(35)N(2))(C(14)H(24)Si(2))(C(4)H(8)O)]·C(7)H(8), was prepared by treatment of anhydrous samarium trichloride with a 1:1 mixture of in situ-prepared Li(DippForm) [DippFormH = N,N'-bis-(2,6-diisopropyl-phen-yl)methanimidamide] and Li(2)(COT'') [COT'' = 1,4-bis-(trimethyl-sil-yl)cyclo-octa-tetra-enyl] in tetra-hydro-furan (THF). Despite the presence of two very bulky ligands (COT'' and DippForm), the mol-ecule still contains one coordinated THF ligand. The overall coordination geometry around the Sm(III) atom resembles a three-legged piano-stool with the COT'' ligand being ?(8)-coordinated and the DippForm(-) anion acting as an N,N'-chelating ligand [Sm-N = 2.5555?(15) and 2.4699?(15)?Å]. The asymmetric unit also contains a disordered mol-ecule of toluene, the refined ratio of the two components being 0.80?(4):0.20?(4).

catena-Poly[[[bis-(methanol-?O)bis-(seleno-cyanato-?N)manganese(II)]-?-1,2-bis-(pyridin-4-yl)ethane-?(2) N:N'] 1,2-bis-(pyridin-4-yl)ethane monosolvate].

Project description:The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are located on centers of inversion while the coordinating N-donor co-ligands are located on a twofold rotation axis. In the crystal, the Mn(II) cations are linked into chains along the c-axis direction by the bpa ligands. The chains are further connected via a non-coordinating bpa ligand into layers parallel to (3-10) via O-H?N hydrogen-bonding inter-actions.

Crystal structures of di-?-bromido-bis{di-bromido-[?5-2-(di-methyl-amino)-inden-yl]zirconium(IV)} and di-bromido-bis-[?5-2-(di-methyl-amino)-inden-yl]zirconium(IV).

Project description:In the title compounds, [Zr2Br6(C11H12N)2], (I) and [ZrBr2(C11H12N)2], (II), the positions of the ?5-binding 2-di-methyl-amino-indenyl units are fixed by intra-molecular C-H?Br inter-actions involving aromatic or di-methyl-amino H atoms. The binuclear mol-ecule of (I) is located on a general position, while the mononuclear mol-ecule of (II) is situated on a twofold rotation axis. Both ZrIV atoms in (I) are ligated by one cyclo-penta-dienyl (CP) ring and four Br ligands (two bridging, two terminal), while in (II) the ZrIV atom is ligated by two CP rings and two terminal Br ligands. The crystal structures of both (I) and (II) comprise of strands of ?-?- and N-?-bonded mol-ecules, which in turn are linked by C-H?Br inter-actions.

Bis(1,10-phenanthroline-κN,N')(sulfato-O)copper(II) ethane-1,2-diol monosolvate.

Project description:In the title compound, [Cu(SO(4))(C(12)H(8)N(2))(2)]·C(2)H(6)O(2), the Cu(II) ion is five-coordinated in a distorted square-pyramidal manner by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and one O atom from a monodentate sulfate anion. The four N atoms comprise a square and the one O atom the apex of a square pyramid. The two chelating N(2)C(2) groups are oriented at 71.1 (2)°. In the crystal, the components are connected by inter-molecular O-H⋯O hydrogen bonding. The presence of pseudosymmetry in the structure suggests the higher symmetry space group C2/c, but attempts to refine the structure in this space group resulted in an unsatisfactory model.
