{?-trans-N,N'-Bis[2-(2-hydroxy-ethyl-amino)eth-yl]oxamidato(2-)}bis-[picrato-nickel(II)].

ABSTRACT: The title complex, [Ni(2)(C(6)H(2)N(3)O(7))(2)(C(10)H(20)N(4)O(4))], contains a centrosymmetric binuclear unit in which the oxamide ligand (located on a centre of symmetry) acts in a bis--tetra-dentate fashion and the picrate anion binds to nickel(II) in a bidentate mode. The Ni(II) atom displays a distorted octa-hedral coordination with axial elongation. The binuclear mol-ecules are linked by inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds into a two-dimensonal supra-molecular network extending parallel to (100).

trans-Bis(ethyl-enediamine)-bis-{2-[N-(2-hy-droxy-eth-yl)oxamoyl-amino]-benzoato}nickel(II).

Project description:The title mononuclear Ni(II) complex, [Ni(C(11)H(11)N(2)O(5))(2)(C(2)H(8)N(2))(2)], is built up by inversion symmetry associated with the central Ni atom. The ethyl-enediamine ligands are non-planar. The r.m.s. deviation from the mean plane of the five-membered Ni-ethyl-amine chelate ring plane is 0.1945 Å. In the crystal structure, complex mol-ecules are linked to each other via N-H⋯O and O--H⋯O hydrogen bonding through translation symmetry along the b and c axes, resulting in an extended supra-molecular network.

Project description:In the title centrosymmetric mononuclear nickel(II) complex, [Ni(C(13)H(20)N(2)O(2))(2)](ClO(4))(2), the Ni(II) atom is four-coordinated by the imine N and phenolate O atoms of the zwitterionic forms of two Schiff base ligands in a square-planar coordination geometry. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the a axis.

Project description:In the toluene hemisolvated tripodal tris-(2-amino-ethyl)amine Schiff base, C(30)H(33)Cl(3)N(4)O(3)·0.5C(7)H(8), one of the three imino N atoms is protonated, forming a hydrogen bond with the O atom at an adjacent benzene ring. The other two imino N atoms act as hydrogen-bond acceptors from phenolate OH groups. The toluene solvent mol-ecule is disordered about a centre of inversion.

Bis[eth-yl(2-hydroxy-ethyl)aza-nium] 2,2'-disulfanediyldibenzoate.

Project description:The asymmetric unit of the title salt, 2C(4)H(12)NO(+)·C(14)H(8)O(4)S(2) (2-), contains an eth-yl(2-hydr-oxy)aminium cation and half a 2,2'-disulfanediyldibenzoate anion, with the latter disposed about a twofold axis. The cation is a straight chain with the exception of the terminal hydr-oxy group [the N-C-C-O torsion angle is 66.5?(2)°]. A twisted conformation is found for the anion [the C-S-S-C torsion angle is 91.51?(9)° and the dihedral angle between the rings is 81.01?(4)°]. A supra-molecular chain with base vector [101] and a tubular topology is formed in the crystal structure mediated by charge-assisted O-H?O(-) and N(+)-H?O(-) hydrogen bonding.
