Bis[tris(propane-1,3-diamine-?(2) N,N')-nickel(II)] di-aqua-bis(propane-1,3-di-amine-?(2) N,N')nickel(II) hexa-bromide dihydrate.

ABSTRACT: In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni(2+) cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni(2+) cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni(2+) cation has an octa-hedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N-H?Br, O-H?Br and O-H?O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

Diaqua-bis-(propane-1,3-diamine)-nickel(II) bis-(propane-1,3-diamine)-disulfato-nickelate(II).

Project description:The ionic Ni(II) title complex, [Ni(C(3)H(10)N(2))(2)(H(2)O)(2)][Ni(SO(4))(2)(C(3)H(10)N(2))(2)], is built up of [Ni(dipr)(2)(H(2)O)(2)](2+) complex cations and [Ni(dipr)(2)(SO(4))(2)](2-) complex anions (dipr is propane-1,3-diamine). Both Ni(II) atoms display a slightly distorted octa-hedral coordination and are located on inversion centers. There are several types of hydrogen-bonding inter-actions, which connect complex cations and anions into a two-dimensional network parallel to (010). Hydrogen bonds formed by the axially coordinated water mol-ecule of the complex cation and one of the O atoms of the sulfate groups of the complex anion (first type) link them into chains along the c axis. These chains are linked to each other through hydrogen bonds formed by an O atom (second type) of the SO(4) groups and NH(2) groups of the ligand of the complex cations from neighboring chains, forming a two-dimensional hydrogen-bonded net perpendicular to the b axis. The third type of O atoms of the sulfate groups of the complex anion are also linked into chains by a combination of both previously described types of H-atom connections.

Diaqua-bis(1,3-propane-diamine)nickel(II) squarate tetrahydrate.

Project description:The asymmetric unit of the title compound, [Ni(C(3)H(10)N(2))(2)(H(2)O)(2)](C(4)O(4))·4H(2)O, contains one-half of the diaqua-bis(1,3-propane-diamine)nickel(II) cation, one-half of the centrosymmetric squarate anion and two uncoordinated water mol-ecules. In the cation, the Ni(II) atom is located on a crystallographic inversion centre and has a slightly distorted octa-hedral coordination geometry. The six-membered chelate ring adopts a chair conformation. O-H?O hydrogen bonds link the cation and anion through the water mol-ecule, while N-H?O hydrogen bonds link the cation and anion and cation and water mol-ecules. In the crystal structure, inter-molecular O-H?O and N-H?O hydrogen bonds link the mol-ecules into a three-dimensional network structure.

Bis[?-1,3-bis-(di-phenyl-phosphan-yl)propane-?(2) P:P']digold(I) tetra-chloridonickelate(II) diethyl ether monosolvate.

Project description:The title compound, [Au2(C27H26P2)2][NiCl4]·C4H10O, consists of a digold(I) complex cation, an [NiCl4](2-) complex anion and a diethyl ether solvent mol-ecule.

Project description:The title compound, (C3H10N2)2[AlF6]F·3H2O, was obtained using the solvothermal method with aluminium hydroxide, HF and propane-1,3-di-amine as precursors in ethanol as solvent.
