(Naphthalene-2,3-diolato-κO,O')[tris-(2-pyridyl-meth-yl)amine-κN]cobalt(III) hexa-fluoridophosphate hemihydrate.

ABSTRACT: In the title complex, [Co(C(10)H(6)O(2))(C(18)H(18)N(4))]PF(6)·0.5H(2)O, the Co(III) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from a tris-(2-pyridyl-meth-yl)amine ligand and two O atoms from a naphthalene-2,3-diolate ligand. The asymmetric unit contains two complex cations, two hexa-fluoridophosphate anions and one uncoordinated water mol-ecule. In one of the hexa-fluoridophosphate anions, four of the F aroms are disordered over two sets of sites in a 0.632 (11):0.368 (11) ratio. In the crystal, the cations, anions and water mol-ecules are connected by O-H⋯O and O-H⋯F hydrogen bonds. π-π inter-actions are present between the pyridine rings [centroid-centroid distance = 3.814 (1) Å].

Project description:In the title salt, [Co(C(10)H(6)O(2))(C(18)H(18)N(4))](C(24)H(20)B)·C(3)H(6)O·0.5H(2)O, the Co(III) ion in the complex cation is six-coordinated in a rigid octa-hedral N(4)O(2) geometry. The asymmetric unit contains one complete [Co(C(10)H(6)O(2))(C(18)H(18)N(4))](+) unit, one tetraphenylborate counter-anion and one acetone and one water mol-ecule that is located on an inversion centre. All the features of the Co(III) ion are fully consistent with the formulation of the cation as a Co(3+)-catecholate complex. Variable-temperature magnetic measurements in the region 2-380?K show a obvious diamagnetism over the observed temperature range.

Triazido-[tris-(2-pyridyl-κN)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.

Dicyanido[tris-(2-pyridyl-meth-yl)amine]-cobalt(III) hexa-fluorido-phosphate.

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.

(Carbonato-κO,O')bis-(di-2-pyridyl-amine-κN,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.

[(4-Bromo-phen-yl)(2-pyridyl-methyl-idene)amine-κN,N']bis-(1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato-κO,O')cobalt(II).

Project description:In the title complex, [Co(C(5)HF(6)O(2))(2)(C(12)H(9)BrN(2))], the Co(II) atom exhibits a pseudo-octa-hedral coordination geometry, comprising two N-donor atoms from a bidentate chelate (4-bromo-phen-yl)(2-pyridyl-methyl-idene)amine (ppa(Br)) ligand [Co-N = 2.098 (2) and 2.209 (2) Å] and four O-donor atoms from two bidentate chelate 1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionate (hfac) ligands [Co-O range = 2.0452 (19)-2.0796 (19) Å]. The packing of the structure involves weak π-π inter-actions between the pyridyl and benzene rings of neighbouring ppa(Br) ligands [centroid-centroid distance = 3.928 (2) Å] and inter-actions between the Br atom on the ppa(Br) ligand and the hfac ligand [Br⋯C = 3.531 (2) Å].

Bis(2-phenyl-4,6-di-2-pyridyl-1,3,5-triazine-κN,N,N)ruthenium(II) bis(hexa-fluoridophosphate).

Project description:The asymmetric unit of the title compound, [Ru(C(19)H(13)N(5))(2)](PF(6))(2), consists of an Ru(II) complex cation and two hexa-fluoridophosphate anions. The Ru(II) atom is coordinated by three N atoms from the two outer pyridine and the central triazine rings of each of two tridentate ligands in a distorted octa-hedral environment. The ligands are approximately orthogonal to one another, with a dihedral angle of 88.34 (2)° between planes through the three six-membered rings of the two ligands. The pendant phenyl substituents are almost coplanar with the triazine rings to which they are bound, with dihedral angles of 5.41 (9) and 14.90 (10)°. This is reflected in the previously reported photophysical results with an increased lifetime of the triplet metal to ligand charge transfer ((3)MLCT) excited state [Fang, Taylor, Hanan, Loiseau, Passalacqua, Campagna, Nierengarten & Van Dorsselaer (2002). J. Am. Chem. Soc.124, 7912-7913].

(2-Hydroxy-benzoato-κO)[tris-(1-methyl-benzimidazol-2-ylmethyl-κN)amine-κN]cobalt(II) perchlorate dimethyl-formamide sesquisolvate.

Project description:In the title complex, [Co(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·1.5C(3)H(7)NO, the Co(II) ion is five-coordinated by four N atoms from a tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry with approximate mol-ecular C(3) symmetry. The perchlorate ion is disordered over two sites with equal occupancy. One dimethyl-formamide solvent mol-ecule lies on a general position and is disordered over two coplanar orientations with equal occupancy. A second dimethyl-formamide mol-ecule is disordered about a twofold rotation axis. There is an intra-molecular O-H⋯O hydrogen bond in the cation.

cis-Bis(1,10-phenanthroline-κ(2)N,N')bis-(pyridin-4-amine-κN(1))ruthenium(II) bis-(hexa-fluoridophosphate).

Project description:In the title complex, [Ru(C(12)H(8)N(2))(2)(C(5)H(6)N(2))(2)](PF(6))(2), the Ru(II) atom is bonded to two α-diimine ligands, viz. 1,10-phenanthroline (phen), in a cis configuration, in addition with with two 4-amino-pyridine (4Apy) ligands, resulting in a distorted octa-hedral coordination geometry. N-H⋯F hydrogen-bonding inter-actions play an important role in the crystal assembly: 2(1)-screw-axis-related complex mol-ecules and PF(6) (-) counter-ions alternate in helical chains formed along the a axis by means of these contacts. N-H⋯π contacts (H⋯centroid = 3.45 Å) are responsible for cross-linking between the helical chains along [001].

(Dimethyl-formamide-κO)(2-hy-droxy-benzoato-κO,O)[tris-(1-methyl-1H-benzimidazol-2-ylmethyl-κN)amine-κN]manganese(II) perchlorate dimethyl-formamide monosolvate.

Project description:In the title complex, [Mn(C(7)H(5)O(3))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is coordinated in a slightly distorted monocapped trigonal-prismatic geometry. The tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand coordinates in a tetra-dentate mode and the coordination is completed by a bis-chelating salicylate ligand and a dimethyl-formamide ligand. The hy-droxy group and the ortho H atoms of the salicylate ligand were refined as disordered over two sites with occupancies of 0.581 (8) and 0.419 (8). Both disorder components of the hy-droxy group form intra-molecular O-H⋯O hydrogen bonds.

(Di-2-pyridyl-amine-κN,N')[hydro-tris-(3,5-diphenyl-pyrazol-1-yl-κN)borato]nickel(II) bromide dichloro-methane monosolvate.

Project description:In the title compound, [Ni(C(45)H(34)BN(6))(C(10)H(9)N(3))]Br·CH(2)Cl(2), the Ni(II) atom is five-coordinated by the tridentate hydro-tris-(3,5-diphenyl-pyrazol-yl)borate ligand and a bidentate di-2-pyridyl-amine ligand in a distorted square-pyramidal geometry. In the crystal, inter-molecular N-H⋯Br and C-H⋯Br hydrogen bonds link the Ni complex cations and the Br(-) ions, forming a chain along the c axis.
