Bis{?-N-[(dimethyl-amino)-dimethyl-sil-yl]-2,6-dimethyl-anilido}-?N:N';?N':N-dicopper(I).

ABSTRACT: The title compound, [Cu(2)(C(12)H(21)N(2)Si)(2)], is a binuclear Cu(I) complex. The dimeric mol-ecule has an inversion center located at the mid-point of the Cu-Cu bond [Cu-Cu = 2.7209?(7)?Å]. The bidentate ligand behaves in an N:N'-bridging mode, coordinating the metal atoms. The N-Cu-N unit is close to being linear [176.60?(8)°]. The two N atoms exhibit different affinities for the metal atom. The Cu-N(amino) bond is longer than the Cu-N(anilido) bond by 0.079?Å. The core of the mol-ecule, the [Cu-N-Si-N](2) eight-membered ring, adopts a chair configuration.

The title compound, [Cu(2)(C(12)H(21)N(2)Si)(2)], is a binuclear Cu(I) complex. The dimeric mol-ecule has an inversion center located at the mid-point of the Cu-Cu bond [Cu-Cu = 2.7209 (7) Å]. The bidentate ligand behaves in an N:N'-bridging mode, coordinating the metal atoms. The N-Cu-N unit is close to being linear [176.60 (8)°]. The two N atoms exhibit different affinities for the metal atom. The Cu-N(amino) bond is longer than the Cu-N(anilido) bond by 0.079 Å. The core of the mol-ecule, the ...[more]

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.

Crystal structure of bis-{N-[(di-ethyl-amino)-dimethyl-sil-yl]anilido-?(2) N,N'}zinc.

Project description:The title zinc amide, [Zn(C12H21N2Si)2], was prepared by the metathetical reaction of [LiN(SiMe2NEt2)(C6H5)]2 with zinc dichloride. It is mononuclear and the mol-ecule is generated by twofold rotation symmetry. The central Zn(II) atom is N,N'-chelated by each of the two N-silylated anilide ligands in a highly distorted tetra-hedral environment. Two N-Si-N ligands are arranged in a cis fashion around the Zn(II) atom. The Zn-Namine bonds [2.2315?(12)?Å] are much longer than the Zn-Nanilide bonds [1.9367?(11)?Å].

Dichloridobis{N-[(dimethyl-amino)dimethyl-silyl]-2,6-dimethyl-anilido-κN,N'}zirconium(IV).

Project description:The monomeric title zirconium(IV) compound, [Zr(C(12)H(21)N(2)Si)(2)Cl(2)], was prepared by the metathetical reaction of [LiN(SiMe(2)NMe(2))(2,6-Me(2)C(6)H(3))](2) with zirconium tetra-chloride. The Zr(IV) atom is N,N'-chelated by the N-silylated anilido ligand. Along with two Cl atoms, the six-coordinated Zr(IV) atom demonstrates a highly distorted octa-hedral geometry. The two ligands around the Zr(IV) atom are arranged cis to each other and obey the C(2) symmetry operation. That means the asymmetric unit consists of only half of the mol-ecular compound and the complete mol-ecule is generated by a twofold axis. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal center. The Zr-N(amino) bond is longer than the Zr-N(anilido) bond.

Project description:The title iron(III) compound, [Fe(C(12)H(21)N(2)Si)(2)Cl], is monomeric. The Fe atom is N,N'-chelated by the N-silylated anilide ligand. The two ligands around the Fe atom are arranged trans to each other. The Fe-N(amino) bond is longer than the Fe-N(anilide) bond by about 0.37 Å. The mol-ecule displays a pseudo-twofold rotation. The five-coordinate Fe 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.

Chlorido{?-2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolato}-?-oxido-dicopper(II) trihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(14)H(20)ClN(4)O)ClO]·3H(2)O, one Cu(II) cation assumes a distorted square-planar coordination geometry and the other a distorted square-pyramidal coordination geometry. Both Cu(II) cations are N,N',O-chelated by one arm of the 2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolate anion, and one oxide anion bridges the two Cu(II) cations, forming a dinuclear complex. One of the Cu(II) cations is further coordinated by an Cl(-) anion in the apical direction. In the crystal, lattice water mol-ecules are linked with the complex mol-ecule via O-H?Cl hydrogen bonds while O-H?O hydrogen bonding occurs between lattice water mol-ecules , forming three-dimensional network structure.
