Dichlorido{N,N-dimethyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine-κN,N',N''}cadmium.

ABSTRACT: In the title compound, [CdCl(2)(C(11)H(17)N(3))], the Schiff base acts as an N,N',N''-tridentate ligand towards the Cd(II) ion. Two Cl atoms complete a distorted square-pyramidal geometry around the metal atom. In the crystal, a C-H⋯Cl inter-action connects pairs of mol-ecules into centrosymetric dimers.

Project description:The Zn(II) atom in the title complex, [ZnCl(2)(C(8)H(12)N(4))], is coordinated by two Cl atoms and three N atoms of the N-[1-(pyrazin-2-yl)ethyl-idene]ethane-1,2-diamine ligand, and displays a distorted square-pyramidal geometry with the apical position occupied by a Cl atom.

Project description:The asymmetric unit of the title compound, [MnCl(2)(C(11)H(17)N(3))], contains two crystallographically independent mol-ecules with slightly different geometries. In each mol-ecule, the Mn(II) ion is five coordinated by the N,N',N''-tridentate Schiff base and two Cl atoms in a distorted square-pyramidal geometry.

Dichlorido{N,N-dimethyl-N'-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine-?N,N',N''}zinc.

Project description:The asymmetric unit of the title compound, [ZnCl(2)(C(11)H(17)N(3))], contains two independent penta-coordinate Zn(II) complex mol-ecules. In each mol-ecule, the metal atom is coordinated by an N,N',N''-tridenate Schiff base and two Cl atoms in a distorted square-pyramidal geometry. The two mol-ecules differ little in their geometry, but more in their inter-molecular inter-actions. In the crystal, adjacent mol-ecules are connected via C-H?Cl inter-actions into a three-dimensional supra-molecular structure. The network is supplemented by ?-? inter-actions formed between the aromatic rings of pairs of the symmetry-related mol-ecules [centroid-centroid distances = 3.6255?(10) and 3.7073?(10)?Å]. The crystal lattice contains void spaces with a size of 52?Å(3).

Dichlorido{N-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine}copper(II).

Project description:The title complex, [CuCl(2)(C(9)H(13)N(3))], is mononuclear and contains a five-coordinate Cu(II) atom. The geometry of the Cu(II) atom can be described as tetra-gonal-pyramidal derived from the calculation of the value τ = 0.102. The three N atoms of the pyridine and ethane-1,2-diamine ligands and one Cl atom belong to the basal plane and the other Cl atom represents the axial position of the pyramid. The Cu atom is displaced by 0.2599 (2) Å from the basal plane towards the axial Cl atom. In the crystal, mol-ecules are linked into chains by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds.

Project description:In the title compound, [Ni(NCS)(2)(C(11)H(17)N(3))(H(2)O)], the Ni(II) ion is six-coordinated by the N,N',N"-tridentate Schiff base N atoms, two cis-positioned N-bound isothio-cyanate groups and one water mol-ecule. In the crystal, O-H⋯S hydrogen bonds link adjacent mol-ecules into infinite layers parallel to the ac plane. The layers are further connected into a three-dimensional network via C-H⋯π inter-actions. The -CH(2)-N(CH(3))(2) fragment is disordered over two sets of sites in a 0.556 (5):0.444 (5) ratio.

Bis{N-methyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine}-zinc bis-(perchlorate).

Project description:The title mononuclear zinc(II) complex, [Zn(C(10)H(15)N(3))(2)](ClO(4))(2), was obtained by the reaction of 2-acetyl-pyridine, N-methyl-ethane-1,2-diamine and zinc perchlorate in methanol. The asymmetric unit of the complex contains two independent [Zn(C(10)H(15)N(3))(2)](2+) cations and four perchlorate anions. The Zn(II) atom in each complex cation is six-coordinated by two pyridine N, two imine N and two amine N atoms from two N-methyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine Schiff base ligands in a distorted octa-hedral geometry. The pyridine rings in each of the complex cations are approximately perpendicular to each other, making dihedral angles of 88.4?(3) and 87.9?(3)°. The perchlorate anions are linked to the complex cations through N-H?O hydrogen bonds.

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.
