Cis-Aqua-bromidobis(di-2-pyridyl-amine-?N,N')manganese(II) bromide.

ABSTRACT: In the title compound, [MnBr(C(10)H(9)N(3))(2)(H(2)O)]Br, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)BrO octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands, one Br(-) anion and one O atom of a water ligand. As a result of the different trans effects of Br, N and O atoms, the Mn-N bond trans to the Br atom is slightly longer than the Mn-N bond trans to the N or O atoms. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.2?(4) and 28.2?(3)°. The complex cations and the Br(-) anions are linked by inter-molecular O-H?Br and N-H?Br hydrogen bonds. Inter-molecular ?-? inter-actions are present between the pyridine rings, with a centroid-centroid distance of 3.793?(4)?Å.

The Mn-O distances range from 2.151?(2) to 2.5093?(19)?Å, while the Mn-N distances are 2.226?(2) and 2.248?(2)?Å. Each 5-ferrocenyl-benzene-1,5-dicarboxyl-ate anion links to two Mn(II) ions, resulting in a chain along the b axis. A three-dimensional network of N-H?O and O-H?O hydrogen bonds helps to stabilize the crystal packing.

(Di-2-pyridyl-amine)-(methanol)sulfato-copper(II).

Project description:The title complex, [Cu(SO(4))(C(10)H(9)N(3))(CH(3)OH)], is a mononuclear species with the Cu(II) ion in a Jahn-Teller-distorted '4 + 1' square-pyramidal geometry. The basal plane is defined by the pyridyl N-atom donors of the bipyridyl-amine (bpa) ligand and two O-atom donors of the sulfate ligand. The coordination geometry is completed by the axial coordination of a methanol O-atom donor. The axial bond length displays the usual elongation: Cu-O(axial) = 2.168?(2), Cu-O(basal) = 2.016?(2) (average) and Cu-N(basal) = 1.951?(3)?Å (average). In the crystal structure, the complex mol-ecules are linked through N-H?O and O-H?O hydrogen bonds into chains along [100].

(Carbonato-?O,O')bis-(di-2-pyridyl-amine-?N,N')cobalt(III) bromide.

Project description:In the title compound, [Co(CO(3))(C(10)H(9)N(3))(2)]Br, a distorted octa-hedral coordination of the Co(III) atom is completed by four N atoms of the two chelating di-2-pyridyl-amine ligands and two O atoms of the chelating carbonate anion. The di-2-pyridyl-amine ligands are nonplanar and the dihedral angles between the 2-pyridyl groups are 29.11?(9) and 37.15?(12)°. The coordination cation, which has approximate C(2) symmetry, is connected to the bromide ion via an N-H?Br(-) hydrogen bond. The ionic pair thus formed is further assembled into a dimer via N-H?O inter-actions about an inversion centre. A set of weaker C-H?O and C-H?Br(-) inter-actions connect the dimers into a three-dimensional network.

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.
