Bis{N-[(diethyl-amino)-dimethyl-sil-yl]anilinido-?(2)N,N'}nickel(II).

ABSTRACT: The mononuclear Ni(II) amide, [Ni(C(12)H(21)N(2)Si)(2)], has the Ni(II) atom N,N'-chelated by the N-silylated anilinide ligands. The ligands are arranged cis to each other and obey the C(2)-symmetry operation. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom: the Ni-N(anilinide) bond length is 1.913?(3)?Å and Ni-N(amine) is 2.187?(3)?Å. The four-coordinate Ni(II) ion demonstrates a distorted tetra-hedral geometry.

The mononuclear Ni(II) amide, [Ni(C(12)H(21)N(2)Si)(2)], has the Ni(II) atom N,N'-chelated by the N-silylated anilinide ligands. The ligands are arranged cis to each other and obey the C(2)-symmetry operation. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom: the Ni-N(anilinide) bond length is 1.913 (3) Å and Ni-N(amine) is 2.187 (3) Å. The four-coordinate Ni(II) ion demonstrates a distorted tetra-hedral geometry. ...[more]

Diaqua-bis(N,N-diethyl-nicotinamide-?N)bis-[4-(dimethyl-amino)benzoato-?O]nickel(II).

Project description:The centrosymmetric title Ni(II) complex, [Ni(C(9)H(10)NO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two dimethyl-amino-benzoate (DMAB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules, all of them monodentate. The four O atoms in the equatorial plane around the Ni(II) atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the DENA ligands in axial positions. The Ni(II) atom is displaced by 0.681?(1)?Å out of the least-squares plane of the carboxyl-ate group. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 5.61?(7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 73.20?(4)°. An intra-molecular O-H?O hydrogen bond results in the formation of a six-membered ring with a twisted conformation. In the crystal structure, inter-molecular O-H?O and C-H?O hydrogen bonds link mol-ecules into a three-dimensional network. Two weak C-H?? inter-actions are also present.

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

Project description:In the title compound, [Ni(C(6)H(6)NO(3)S)(2)(C(3)H(7)NO)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) ion (site symmetry ) is coordinated by two -NH(2) groups from two 4-amino-benzene-sulfonate anions, two O atoms from two dimethyl-formamide mol-ecules and two water mol-ecules, forming a slightly distorted trans-NiN(2)O(4) octa-hedral geometry. In the crystal structure, inter-molecular O-H?O, O-H?(O,O) and N-H?O hydrogen bonds link the components into a three-dimensional network. The O atoms of the sulfonate group are disordered over two sets of sites in a 0.833?(4):0.167?(4) ratio and the O atom of the uncoordinated water mol-ecule is disordered over two sites in a 0.637?(18):0.363?(18) ratio.
