Bis(propane-1,3-diamine)-disaccharinatonickel(II).

ABSTRACT: In the title complex, [Ni(C(7)H(4)NO(3)S)(2)(C(3)H(10)N(2))(2)] or [Ni(sac)(2)(pen)(2)] (sac = saccharinate or 1,1,3-trioxo-2,3-dihydro-1?(6,2)-benzothia-zol-2-ide and pen = propane-1,3-diamine), the Ni(II) ion sits on an inversion center, being coordinated by two N atoms of the sac ligands, which occupy trans positions, and four N atoms of the bidentate pen ligands to define a distorted octa-hedral geometry. The pen ligands chelate the metal ion, forming a six-membered ring which adopts a half-chair conformation, while the sac ligands adopt the most common coordination mode. The crystal packing is stabilized by N-H?O hydrogen bonds, which form a one-dimensional network along [010]. It is also supported by an N-H?S hydrogen bond between the amine group of the pen ligand and the sulfonyl group of the sac ligand.

Diazido-bis(propane-1,3-diamine)copper(II).

Project description:In the title complex, [Cu(N(3))(2)(C(3)H(10)N(2))(2)], the Cu(II) ion resides on a centre of symmetry and is in a Jahn-Teller distorted octa-hedral coordination environment comprising two N atoms from azide anions in axial positions and four N atoms from propane-1,3-diamine (tn) ligands in equatorial positions.

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[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.

Project description: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.

Project description:There are three different Mn(II) complexes in the asymmetric unit of the title compound, [Mn(C(15)H(16)N(4))(H(2)O)(2)]Br(2)·2{[MnBr(C(15)H(16)N(4))(H(2)O)]Br}·[MnBr(2)(C(15)H(16)N(4))]. In the neutral complex, the Mn(2+) ion is six-coordinated in a distorted octa-hedral environment by four N atoms of the tetra-dentate ligand N,N'-bis-(2-pyridylmethyl-ene)propane-1,3-diamine (bppd) and two bromide ligands.

The complexes with two coordinated Br atoms or two H(2)O ligands are disposed about a twofold axis through Mn and C atoms with the special positions (, y, 0) and (0, y, ), respectively. The compound displays inter-molecular O-H?Br hydrogen bonding. There are inter-molecular ?-? inter-actions between adjacent pyridine rings, with centroid-centroid distances of 3.822 and 3.833 Å, and a C-H?O inter-action is also present.
