Chlorido{N-[(diethyl-amino)-dimethyl-sil-yl]anilido-κN}(N,N,N',N'-tetra-methyl-ethane-1,2-diamine-κN,N')cobalt(II).

ABSTRACT: In the title cobalt(II) compound, [Co(C(12)H(21)N(2)Si)Cl(C(6)H(16)N(2))], the ethane-1,2-diamine donor mol-ecule coordin-ates the metal atom in an N,N'-chelating mode, with Co-N distances of 2.136 (2) and 2.140 (3) Å. An anilide ligand connects to the Co(II) atom with a σ-bond, the Co-N(anilide) distance being 1.931 (2) Å. The four-coordinate Co(II) atom demonstrates a slightly distorted tetra-hedral geometry.

Tris(ethane-1,2-diamine-κN,N')cobalt(III) carbonate iodide tetra-hydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](CO(3))I·4H(2)O, crystallizes with a [Co(en)(3)](3+) cation (en is ethane-1,2-diamine), CO(3) (2-) and I(-) anions and four water mol-ecules in the asymmetric unit. In the cation, the three rings formed by the ethyl-enediamine units and the Co(III) metal ion are in slightly distorted twist conformations. Numerous O-H⋯O, N-H⋯O, N-H⋯I and O-H⋯I inter-molecular hydrogen bonds between the cation and two anions in concert with the four water mol-ecules dominate the crystal packing and create a supra-molecular infinite three-dimensional framework.

Bis[μ-N-(diethyl-amino-κN)dimethyl-silylanilido-κN:N]bis-[chlorido-cobalt(II)].

Project description:In the title binuclear Co(II) complex, [Co(2)(C(12)H(21)N(2)Si)(2)Cl(2)], an inversion center is located at the mid-point between the two Co atoms in the dimeric mol-ecule. The bidentate N-silylated anilide ligand coordinates the Co(II) atom in an N,N'-chelating mode and provides the anilide N atom as a bridge to link two Co(II) atoms. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom. The Co-N(anilide) bond is 2.031 (6) Å and Co-N(amino) bond is 2.214 (6) Å. The four-coordinate Co atom presents a distorted tetra-hedral geometry, while the dimeric aggregation exhibits a (CoN)(2) rhombus core with 1.998 (6) Å as the shortest sides and shows a ladder structure composed of Co, N and Si atoms.

Chloridobis{N-[(dimethyl-amino)-dimethyl-sil-yl]-2,6-dimethyl-anilido-κN,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.

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

Project description: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.

(μ-Ethane-1,2-diamine-κN:N')bis-[bis-(ethane-1,2-diamine-κN,N')zinc(II)] tetra-kis-(perchlorate).

Project description:In the title salt, [Zn(2)(C(2)H(8)N(2))(5)](ClO(4))(4), an ethyl-enediamine mol-ecule bridges two bis-(ethyl-enediamine)-zinc units; the five-coordinate Zn atoms show a trigonal-bipyramidal coordination geometry that is distorted towards square-pyramidal (that of one Zn atom is distorted by 12% and that of the other by 34%). The perchlorate ions are all disordered over two positions in a 1:1 ratio. The cation inter-acts weakly with the anion by N-H⋯O hydrogen bonds, generating a three-dimensional network.

Tris(ethane-1,2-diamine-κN,N')cobalt(II) cis-aqua-2κO-μ-cyanido-1:2κC:N-hepta-cyanido-1κC-bis-(ethane-1,2-diamine-2κN,N')cobalt(II)molybdenum(IV) dihydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)][CoMo(CN)(8)(C(2)H(8)N(2))(2)(H(2)O)]·2H(2)O, is isostructural with the Ni(II) analogue. The Mo(IV) atom is coordinated by eight cyanide ligands, one of which forms a bridge to a Co(II) atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water mol-ecule. Another Co(II) complex, coordinated to three bidentate en ligands, acts as the counter-ion. The crystal structure contains O-H⋯N/O, N-H⋯N/O and C-H⋯N/O hydrogen bonds, which form a three-dimensional network.
