Chloridobis{2-[(dimethyl-amino)-meth-yl]phen-yl}anti-mony(III).

ABSTRACT: In the title compound, [Sb(C(9)H(12)N)(2)Cl], the Sb atom adopts a Ψ-trigonal-bipyramidal geometry. The two 2-[(dimethyl-amino)-methyl]-phenyl ligands are coordinated asymmetrically to the Sb atom. The carbon atoms of one of the ligands are disordered over sets of sites with equal occupancy, resulting in two conformational isomers in the crystal. The Sb-C and Sb-N distances in the ordered ligand are: 2.153 (4) and 3.326 (5) Å, respectively. The corresponding distances in the disordered ligand are: 2.103 (5)/2.188 (5) and 2.454 (3) Å, respectively. The structure displays intra-molecular C-H⋯Cl hydrogen bonding.

Substitutional disorder in the ionic diorganoanti-mony halide adduct [bromido/chlorido(0.33/0.67)][2-(di-methyl-amino-meth-yl)phen-yl][2-(di-methyl-ammonio-meth-yl)phen-yl]anti-mony(III) 0.75-bromide 0.25-chloride.

Project description:The title complex, [SbBr(0.33)Cl(0.67)(C(9)H(13)N)(C(9)H(12)N)]Br(0.75)Cl(0.25), exhibits substitutional disorder of both halogen atoms in the asymmetric unit, however, with different occupancies. Thus, the halogen atom bonded to Sb has 0.67?(4) occupancy for Cl and 0.33?(4) for Br, while the anionic halogen atom shows 0.75?(4) occupancy for Br and 0.25?(4) for Cl. An N-H?Cl/Br hydrogen bond is established between the cation and the halide anion. The coordination geometry of the Sb center in the cation is distorted pseudo-trigonal-bipyramidal as a result of the strong intra-molecular N?Sb coordination trans to the Sb-Cl/Br bond. The pendant arm on the second ligand is twisted away from the metal center. The compound crystallizes as a racemate, i.e. a mixture of (R(N2),C(Sb1)) and (S(N2),A(Sb1)) isomers with respect to planar chirality induced by the coordinating N atom and chelate-induced Sb chirality. These isomers are associated through C(phen-yl)-H?Cl/Br hydrogen bonds, forming a three-dimensional architecture.

Chloridobis{N-[(dimethyl-amino)-dimethyl-sil-yl]-2,6-dimethyl-anilido-?N,N'}titanium(III).

Project description:In the monomeric title titanium(III) compound, [Ti(C(12)H(21)N(2)Si)(2)Cl], the metal atom is surrounded by two N-silylated anilide ligands in an N,N''-chelating mode. The two ends of the N-Si-N chelating unit exhibit different affinity to the metal center. The Ti-N(amine) bond is longer than the Ti-N(anilide) bond by about 0.29?Å. The two ligands are arranged trans to each other and the mol-ecule demonstrates a pseudo-twofold rotation along the axis of the Ti-Cl bond. The five-coordinate Ti atom demonstrates a highly distorted trigonal-bipyramidal geometry.

[2,6-Bis(dimethyl-amino-meth-yl)phen-yl]selenium bromide monohydrate.

Project description:In the title hydrated molecular salt, C(12)H(19)N(2)Se(+)·Br(-)·H(2)O, the two independent bromide anions lie on a twofold rotation axis. Strong intra-molecular N→Se inter-actions [2.185 (3) and 2.181 (3) Å] are established by both N atoms of the organic group in the cation, in trans positions to each other, with an N-Se-N angle of 161.6 (1)°, resulting in a T-shaped (C,N,N')Se core. In the crystal, dimeric associations are formed by Br⋯Se [3.662 (2) Å] and Br⋯H inter-actions [2.56 (6) and 2.63 (7) Å] involving two bromide anions, two cations and two water mol-ecules.
