μ-Methyl-ene-bis-[di-bromido(diethyl ether-κO)aluminium(III)]: crystal structure and chemical exchange in solution.

ABSTRACT: In the title compound, [Al₂Br₄(CH₂)(C₄H₁₀O)₂], the mol-ecule lies on a crystallographic twofold axis passing through the bridging C atom. Each Al^III atom is four-coordinate, being bonded to two bromide ions, bridging the CH₂ group as well as the oxygen atom of a diethyl ether ligand in a slightly distorted tetra-hedral arrangement with angles ranging from 101.52 (8) to 116.44 (5)°. The Al-CH₂-Al angle, 118.4 (2)°, is the smallest observed for a structure where this moiety is not part of a ring. In the crystal, weak C-H⋯Br inter-actions, characterized as R ² ₂(12) rings, link the mol-ecules into ribbons in the [101] direction. The title compound is monomeric and coordinatively saturated in the solid state, as each aluminum is four-coordinate, but in solution the ether mol-ecules from either or both Al atoms can dissociate, and would be expected to rapidly exchange, and this is supported by NMR data.

Di-?-bromido-bis-[benz-yl(diethyl ether)magnesium].

Project description:The title benzyl Grignard reagent, [Mg(2)Br(2)(C(7)H(7))(2)(C(4)H(10)O)(2)], was obtained by reaction of benzyl bromide with magnesium in diethyl ether, followed by crystallization from toluene. The asymmetric unit comprises one half-mol-ecule, the structural dimeric unit being generated by inversion symmetry with an Mg?Mg distance of 3.469?(2)?Å. The Mg(II) atom exhibits a distorted tetrahedral coordination geometry. The crystal packing is defined by van der Waals inter-actions only.

Project description:The crystal structure of the title compound, [Mg2Br2(C9H11)2(C4H10O)2], features a centrosymmetric two-centre magnesium complex with half a mol-ecule in the asymmetric unit. The Mg atom is in a considerably distorted Br2CO coordination. Bond lengths and angles are comparable with already published values. The crystal packing is stabilized by C-H⋯π inter-actions linking the complexes into sheets parallel to (0-11).

Bis[μ-1,3-bis-(di-phenyl-phosphan-yl)propane-κ(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.

Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]].

Project description:Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra are rotated and tilted due to N-H⋯Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetra-chloridoplumbate (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].

Project description:In the centrosymmetric dinuclear copper(I) complex cation of the title compound, [Cu2(C28H28P2)3](PF6)2·2C4H10O, the Cu(I) atom is bonded to three P atoms of two butane-1,4-diylbis(di-phenyl-phosphane) (dppb) ligands with a triangular coordination geometry. One of these P atoms belongs to a bridging dppb ligand [Cu-P = 2.2381 (5) Å] and two belong to a chelating dppb ligand [Cu-P = 2.2450 (6) and 2.2628 (5) Å]. The bridging dppb ligand lies on an inversion centre. In the crystal, the cation and the PF6 (-) anion are linked by C-H⋯F inter-actions, forming a tape along [110]. The cation and the diethyl ether solvent mol-ecule are also linked by a C-H⋯O inter-action.

Crystal structure of (μ-N-allyl-thio-urea-κ(2) S:S)bis-[μ-bis-(di-phenyl-phosphanyl)methane-κ(2) P:P']bis-[bromido-copper(I)] aceto-nitrile disolvate.

Project description:The reaction of cuprous bromide with a mixture of 1,1-bis-(di-phenyl-phosphan-yl)methane (dppm: C25H22P2) and N-allyl-thio-urea (ATU: C4H8N2S) in aceto-nitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU)(dppm)2]·2CH3CN. Both Cu(+) ions adopt distorted tetra-hedral geometries, being coordinated by one terminal Br atom, one μ(2)-S atom of the bridging ATU ligand and two P atoms of the bridging dppm ligands. Within the complex, intra-molecular C-H⋯S, C-H⋯π, N-H⋯Br and π-π stacking inter-actions are observed. In the crystal, the components are linked by N-H⋯Br and C-H⋯N hydrogen bonds and weak π-π stacking inter-actions, generating chains propagating in the [100] direction.
