Bis(2,3-dimethyl-butane-2,3-diamine)nickel(II) dinitrate monohydrate.

Project description:In the title compound, [Ni(C(6)H(16)N(2))(2)](NO(3))(2)·H(2)O, the bis-(2,3-dimethyl-butane-2,3-diamine)nickel(II) complex cation possesses a relatively undistorted square-planar geometry about the Ni atom, which lies on an inversion centre and is coordinated by four N atoms from two symmetry-related 2,3-diamino-2,3-dimethyl-butane (tmen) ligands. The amine groups are N-H?O hydrogen bonded to the nitrate anions, which are, in turn, linked by inter-stitial water mol-ecules lying on a twofold axis. The infinite zigzag chains thus formed along [001] are further connected to each other by N-H?O hydrogen bonds towards the water mol-ecules, forming layers of two-dimensional hydrogen-bonded arrays.

1,4-Dichloro-2,3-bis-(chloro-meth-yl)butane.

Project description:The title compound, C6H10Cl4, adopts a geometric arrangement with two C-Cl bonds anti-periplanar to C-H bonds and the other two anti-periplanar to C-C bonds. While minimising steric replusion, this arrangement still gives rise to some intramolecular C-H?Cl contacts. In the crystal, mol-ecules are connected into a three-dimensional architecture via further C-H?Cl contacts.

2,3-Bis{[2,3-dimethyl-6-(phenyl-vin-yl)phen-yl]imino}-butane.

Project description:In the title compound, C36H36N2, a product of the condensation reaction of 2,3-dimethyl-6-phenyl-vinyl-benzenamine and 2,3-butane-dione, the complete mol-ecule is generated by the application of an inversion centre. The central C-C bond in the 1,4-di-aza-butadiene fragment is trans-configured and situated about the inversion center. The dihedral angle between the ring attached to N and the 1,4-di-aza-butadiene plane is 78.24?(36)°, while the 1,4-di-aza-butadiene plane makes an angle of 30.71?(26)° with the phenyl ring.

Bis(1,10-phenanthroline-?N,N')(sulfato-?O,O')cobalt(II) butane-2,3-diol monosolvate.

Project description:In the title compound, [Co(SO(4))(C(12)H(8)N(2))(2)]·C(4)H(10)O(2), the Co(2+) ion has a distorted octa-hedral coordination environment composed of four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from an O,O'-bidentate sulfate anion.

The Co(2+) ion, the S atom and the mid-point of the central C-C bond of the butane-2,3-diol solvent mol-ecule are situated on twofold rotation axes. The mol-ecules of the complex and the solvent mol-ecules are held together by pairs of symmetry-related O-H?O hydrogen bonds with the uncoordinated O atoms of the sulfate ions as acceptors. The solvent mol-ecule is disordered over two sets of sites with site occupancies of 0.40 and 0.60.
