{?-5-[1,3-Bis(2,4,6-trimethyl-phen-yl)-3H-imidazolium-2-yl]-2-(2-oxoethenyl-1?C)furan-3-yl-2?C}-?-hydrido-bis(tetra-carbonyl-rhenium) tetra-hydro-furan 0.67-solvate.

ABSTRACT: The title complex, [Re(2)(C(27)H(25)N(2)O(2))H(CO)(8)]·0.67C(4)H(8)O, was formed as a product in the reaction of a rhenium(I)-Fischer carbene complex with a free NHC carbene. The coordination environment about the two Re atoms is slightly distorted octahedral, including a bridging H atom. The imidazolium and furan groups are almost coplanar, whereas the mesityl substituents show an almost perpendicular arrangement with respect to both heterocyclic units. Mol-ecules of the complex pack in such a way as to form channels parallel with the bc unit-cell face diagonal running through the unit face diagonal. These channels are partially occupied by tetra-hydro-furan solvent mol-ecules.

Bis(2,4,6-trimethyl-phen-yl)zinc(II).

Project description:The title compound, [Zn(C(9)H(11))(2)] or Mes(2)Zn (Mes = mesityl = 2,4,6-trimethyl-phen-yl), crystallizes with a quarter of a mol-ecule in the asymmetric unit. The Zn(II) atom is in a strictly linear environment with a Zn-C bond length of 1.951?(5)?Å. Due to the imposed 2/m symmetry, both aromatic rings are coplanar. One of the methyl groups is disordered over two equally occupied positions.

Bis(2,4,6-trimethyl-pyridinium) tetra-bromidozincate.

Project description:In the title compound, (C(8)H(12)N)(2)[ZnBr(4)], the coordination geometry of the anion is approximately tetra-hedral. The Zn-Br bond lengths range from 2.3901?(19) to 2.449?(2)?Å and the Br-Zn-Br angles range from 107.09?(8) to 112.48?(8)°. In the crystal, each [ZnBr(4)](2-) anion is connected to four cations through two N-H?Br and two C-H?Br hydrogen bonds, forming two-dimensional ?(cation)(2)?anion?(cation(2))? sheets parallel to the bc plane. Within each sheet, the anions are arranged in stacks with no significant inter-anion Br?Br inter-actions [the shortest being > 4.3?Å], while the cations are in chains, with weak ?-? stacking inter-actions [centroid-centroid distance = 3.991?Å] between cations inter-acting with the same anion.

Bis[1,3-bis-(2,4,6-trimethyl-phen-yl)-2,3-dihydro-1H-imidazol-2-yl-idene]dichloridodinitro-syltungsten(II) tetra-hydro-furan-d(8) monosolvate.

Project description:The mol-ecular structure of the title compound, [WCl(2)(NO)(2)(C(21)H(24)N(2))(2)]·C(4)D(8)O, displays a distorted octa-hedral arrangement around the W atom with two trans 1,3-bis-(2,4,6-trimethyl-phen-yl)imidazol-2-yl-idene (IMes) carbene ligands in axial positions. The four equatorial positions are occupied by nitrosyl and chloride ligands, which are trans to each other. The C(carbene)-W-C(carbene) bond angle of 173.44?(18)° and the Cl-W-N(nitros-yl) bond angles of 171.34?(11) and 171.32?(13)° deviate only slightly from linearity. The distortion comes from the nitrosyl and chloride ligands which are not fully coplanar since the two N atoms deviate from the WCl(2) plane by -0.279?(4) and 0.272?(4)?Å, respectively. An inter-molecular C-H?O inter-action connects the organometallic mol-ecule and the tetra-hydro-furan-d(8) solvent mol-ecule.

Bis[1,3-bis-(2,4,6-trimethyl-phen-yl)-2,3-dihydro-1H-imidazol-2-yl-idene]dinitros-yl(tetra-hydro-borato-?H,H')tungsten(0).

Project description:In the title paramagnetic 19-electron neutral complex, [W(BH(4))(C(21)H(24)N(2))(2)(NO)(2)], the W(0) atom is coordinated by two 1,3-bis-(2,4,6-trimethyl-phen-yl)imidazol-2-yl-idene (IMes) carbene ligands, two NO groups and two H atoms of an ?(2)-tetra-hydro-borate ligand. Depending on the number of coordination sites (n) assigned to the BH(4) (-) ligand, the coordination geometry of the W atom may either be described as approximately trigonal-bipyramidal (n = 1) or as very distorted octa-hedral with the bridging H atoms filling two coordination positions (n = 2). In the latter case, the coplanar NO groups and bridging H atoms (r.m.s. deviation = 0.032?Å) form one octa-hedral plane, with mutually trans-oriented carbene ligands. In the crystal, mol-ecules are connected via C-H?O inter-actions.

[N,N'-Bis(2,4,6-trimethyl-phen-yl)ethane-1,2-diimine-?(2)N,N']tetra-carbonyl-chromium(0).

Project description:The octa-hedral coordination of the Cr(0) atom in the title compound, [Cr(C(20)H(24)N(2))(CO)(4)], displays some distortion. This is manifested by an exocyclic torsion angle C(mesitylene)-N-Cr-C(carbon-yl) that deviates by more than 20° from planarity. Another structural feature is the significant distortion from linearity of the Cr-C-O angles of the two carbonyl groups that inter-act with both ortho-methyl groups of the two mesitylene rings. The remaining two carbonyl groups overlap with the centres of the mesitylene rings themselves and are linear within <3°.

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).

5-Bromo-2,4,6-trimethyl-3-(4-methyl-phenyl-sulfin-yl)-1-benzo-furan.

Project description:In the title compound, C18H17BrO2S, the dihedral angle between the methyl-phenyl ring and the mean plane of the benzo-furan rung system is 87.0?(2)°. In the crystal, mol-ecules related by inversion are paired into dimers via C-H?O and C-H?? inter-actions. These dimers are further linked by C-H?O hydrogen bonds and ?-? inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.555?(5)?Å], resulting in a three-dimensional supra-molecular network.

5-Bromo-2,4,6-trimethyl-3-(3-methyl-phenyl-sulfin-yl)-1-benzo-furan.

Project description:In the title compound, C18H17BrO2S, the dihedral angle between the mean plane of the benzo-furan ring system and the benzene ring is 68.58?(4)°. In the crystal, mol-ecules are linked via pairs of C-H?O hydrogen bonds into inversion dimers. These dimers are linked by C-H?O hydrogen bonds and ?-? inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.783?(1)?Å], forming a three-dimensional network. In addition, the stacked mol-ecules exhibit inversion-related S?O contacts [3.153?(1)?Å] involving the sulfinyl groups.
