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

ABSTRACT: 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.

Project description:The title complex, [Co(CO(3))(C(10)H(8)N(2))(2)]Br·3H(2)O, is isostructural with the chloride analogue. The six-coordinated octahedral [Co(2,2'-bipy)(2)CO(3)](+) cation (2,2'-bipy is 2,2'-bipyrid-yl), bromide ion and water mol-ecules are linked together via O-H?Br and O-H?O hydrogen bonds, generating a one-dimensional chain.

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

Project description: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.

(Carbonato-?(2)O,O')bis-(5,5'-dimethyl-2,2'-bipyridyl-?(2)N,N')cobalt(III) bromide trihydrate.

Project description:In the title complex, [Co(CO(3))(C(12)H(12)N(2))(2)]Br·3H(2)O, the Co(III) cation has a distorted octa-hedral coordination environment. It is chelated by four N atoms of two different 5,5'-dimethyl-2,2'-bipyridyl (dmbpy) ligands in axial and equatorial positions, and by two O atoms of a carbonate anion completing the equatorial positions. Although the water mol-ecules are disordered and their H atoms were not located, there are typical O?O distances between 2.8 and 3.0?Å, indicating O-H?O hydrogen bonding. The crystal packing is consolidated by C-H?O and C-H?Br hydrogen bonds, as well as ?-? stacking inter-actions between adjacent pyridine rings of the dmbpy ligands, with centroid-centroid distances of 3.694?(3) and 3.7053?(3)?Å.

Bis(di-2-pyridyl-amine-?N,N')bis-(thio-cyanato-?N)nickel(II).

Project description:The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H?S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak ?-? inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777?(4)?Å], forming a three-dimensional assembly.

Triazido-[tris-(2-pyridyl-?N)methyl-amine]cobalt(III).

Project description:The title compound, [Co(N(3))(3)(C(16)H(14)N(4))], was synthesized by hydro-thermal reaction of [Co(NH(3))(6)](NO(3))(3), NaN(3) and tris-(2-pyrid-yl)methyl-amine. The structure contains two independent complexes in the asymmetric unit, with closely comparable geometry. The Co(III) atoms are hexa-coordinated by three N atoms from the tridentate tris-(2-pyrid-yl)methyl-amine ligands and three azide ions in a fac arrangement. N-H?N hydrogen bonds are formed between the amino group and the uncoordinated terminal N atoms of the azide ligands.

Project description:In the title complex, [Co(CN)(2)(C(18)H(18)N(4))]PF(6), the Co(III) atom together with one of the pyridyl rings and two cyanide anions are located on a mirror plane, while the P atom is located on an inversion centre. The Co(III) atom exhibits an octa-hedral geometry, coordinated by four N atoms from the tris-(2-pyridyl-meth-yl)amine ligand with an average Co-N distance of 1.953?(2)?Å, and two cyanide C atoms with an average Co-C distance of 1.895?(2)?Å. The crystal packing is stabilized by inter-molecular C-H?N and C-H?F inter-actions.

cis-Aqua-bis-(di-2-pyridyl-amine-?N,N')iodidomanganese(II) iodide.

Project description:The asymmetric unit of the title compound, [MnI(C(10)H(9)N(3))(2)(H(2)O)]I, contains a cationic Mn(II) complex and an I(-) anion. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)IO octa-hedral environment defined by four N atoms of the two chelating di-2-pyridyl-amine (dpa) ligands, one I(-) anion and one O atom of a water ligand. As a result of the different trans effects of the I, N and O atoms, the Mn-N bond trans to the I atom is slightly longer than the Mn-N bond trans to the N or O atoms. The dpa ligands are not planar, with dihedral angles between the two pyridine rings of 26.2?(4) and 26.5?(4)°. The complex cations are stacked in columns along the a axis and are linked to the anions by inter-molecular O-H?I and N-H?I hydrogen bonds.
