Tris(ethane-1,2-diamine)copper(II) bis-(trifluoro-acetate).

ABSTRACT: In the title complex, [Cu(H(2)NCH(2)CH(2)NH(2))(3)](CF(3)COO)(2), the environment of the Cu atom is distorted octa-hedral, formed by six N atoms from three chelating ethane-1,2-diamine ligands. The Cu-N distances range from 2.050?(2) to 2.300?(2)?Å. This complex cation and the two trifluoro-acetate anions are connected by weak N-H?O and N-H?F hydrogen bonds, forming a three-dimensional framework. In both anions, the F atoms are disordered over two positions; in one the site-occupancy factors are 0.55 and 0.45, in the other the values are 0.69 and 0.31.

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.

{N,N'-Bis[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine-?N,N',N'',N'''}bis-(trifluoro-methane-sulfanato-?O)copper(II).

Project description:A discrete neutral Cu(II) complex, [Cu(CF(3)SO(3))(2)(C(16)H(18)N(4))], has been derived from the symmetrical tetra-dentate Schiff base, N,N'-bis-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine. The copper centre assumes a tetra-gonally distorted pseudo-octa-hedral geometry with the O atoms of two trifluoro-methane-sulfonate anions coordinated weakly in the axial positions. The Cu-N distances lie in the range 1.941?(3)-2.011?(3)?Å and the Cu-O distances are 2.474?(3) and 2.564?(3)?Å.

Project description:In the title compound, [Ni(C(2)H(8)N(2))(3)](2)[Mo(CN)(8)]·5H(2)O, the Ni(II) ion is coordinated by six N atoms from three ethane-1,2-diamine ligands in a distorted octa-hedral geometry, while the Mo(IV) atom is coordianted by eight cyanide ligands.

Bis(N-phenyl-ethane-1,2-diamine)dithio-cyanato-nickel(II).

Project description:The asymmetric unit of the title mononuclear Ni(II) compound, [Ni(NCS)(2)(C(8)H(12)N(2))(2)], contains two independent half-mol-ecules, the Ni atoms of which lie on crystallographic inversion centres. Each Ni(II) ion is chelated by two N atoms from two N-phenyl-ethane-1,2-diamine ligands and is also coordinated by two N atoms from two thio-cyanate ligands, giving a distorted octa-hedral geometry. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (100) by N-H?S inter-actions.

Di-?-hydroxido-bis-[hemiaqua-(N,N,N',N'-tetra-methyl-ethane-1,2-diamine)-copper(II)] bis-(tetra-fluoridoborate).

Project description:The title compound, [Cu(2)(OH)(2)(C(6)H(16)N(2))(2)(H(2)O)](BF(4))(2), consists of dinuclear centrosymmetric [Cu(2)(OH)(2)(tmen)(2)(H(2)O)](2+) complex cations (tmen = N,N,N',N'-tetra-methyl-ethane-1,2-diamine) and tetra-fluoridoborate anions. In the cation, the Cu(II) atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of ?-OH(-) anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water mol-ecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598?(9):0.269?(6):0.134?(8). The crystal packing is governed by ionic forces as well as by O-H?F hydrogen bonds.

N,N'-Bis[2-chloro-5-(trifluoro-meth-yl)benzyl-idene]ethane-1,2-diamine.

Project description:The mol-ecule of the title Schiff base compound, C(18)H(12)Cl(2)F(6)N(2), adopts an E configuration with respect to the azomethine C=N bond. Intra-molecular C-H?F (× 2) and C-H?Cl (× 2) hydrogen bonds generate S(5) ring motifs. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the methyl-ene bridge, as indicated by the dihedral angle between the two benzene rings of 3.74?(6)°. The inter-esting features of the crystal structure are weak inter-molecular Cl?N and F?F inter-actions, with distances of 2.9192?(11) and 3.2714?(10)?Å, respectively, which are shorter than the sum of the van der Waals radii of the relevent atoms. These inter-actions link neighbouring mol-ecules into dimers which are stacked down the b axis.

Bis(acetato-?O)[N,N,N',N'-tetra-methyl-ethane-1,2-diamine-?N,N']copper(II).

Project description:In the title compound, [Cu(C(2)H(3)O(2))(2)(C(6)H(16)N(2))], the Cu(II) atom is coordinated by two N atoms from the chelating N,N,N',N'-tetra-methyl-ethane-1,2-diamine ligand and two O atoms from two acetate anions in a distorted square-planar geometry. In addition, there are longer contacts between Cu and the second O atom of each acetate ligand, which could be considered to complete a distorted octa-hedral geometry. The mol-ecules in the crystal structure are connected via inter-molecular C-H?O hydrogen-bonding contacts.
