(Acetyl-acetonato-?O,O')bis-[5-meth-oxy-2-(naphth[1,2-d][1,3]oxazol-2-yl)phenyl-?C,N]iridium(III).

ABSTRACT: In the title compound, [Ir(C(18)H(12)NO(2))(2)(C(5)H(7)O(2))], the Ir atom is O,O'-chelated by the acetyl-acetonate group and C,N-chelated by the 2-aryl-naphth[1,2-d]oxazole groups. The six-coordinate metal atom displays a distorted octa-hedral geometry. Intra-molecular C-H?O hydrogen bonds occur. In the crystal, inter-molecular C-H?O hydrogen bonds link the mol-ecules into columns parallel to the b axis.

Bis(acetyl-acetonato-κO,O')-aqua-(diacetyl-methanido-κC)iridium(III).

Project description:In the crystal structure of the title compound, [Ir(C(5)H(7)O(2))(3)(H(2)O)], the Ir(III) atom is six-coordinated and situated in a slightly distorted octa-hedral environment. The complex contains both Ir-O and Ir-C bonds and was isolated from a reaction mixture of IrCl(3)(H(2)O)(x), pentane-2,5-dione and NaHCO(3). O-H⋯O hydrogen bonding between the water molecules and the carbonyl O atoms of adjacent molecules leads to a layered motif extending parallel to (010).

(Acetyl-acetonato-κO,O')bis-[2-(5-methyl-3-phenyl-pyrazin-2-yl-κN)phen-yl-κC]iridium(III).

Project description:In the title complex, [Ir(C(17)H(13)N(2))(2)(C(5)H(7)O(2))], the Ir(III) atom is hexa-coordinated in a distorted octa-hedral geometry by two C,N-bidentate 2-(5-methyl-3-phenyl-pyrazin-2-yl)phenyl (mdpp) ligands and one O,O-bidentate acetyl-acetonate ligand. The dihedral angles between the phenyl rings and the pyrazine ring are 9.56 (14) and 58.99 (14)° for one mdpp ligand and 9.34 (14) and 79.94 (15)° for the other.

(Acetyl-acetonato-κO,O')chlorido-trimethano-latoniobium(V).

Project description:In the title compound, [Nb(CH(3)O)(3)(C(5)H(7)O(2))Cl], the Nb(V) atom is coordinated by two O atoms from the chelating acetyl-acetonate ligand, three O atoms from the methano-late groups and one chloride ligand. The octa-hedral environment around niobium is slightly distorted with Nb-O distances in the range 1.8603 (15)-2.1083 (15) Å and an Nb-Cl distance of 2.4693 (9) Å. The O-Nb-O angles vary between 80.74 (6) and 100.82 (7)°, while the trans Cl-Nb-O angle is 167.60 (5)°. There are no hydrogen bonds observed, only an inter-molecular C-H⋯O inter-action.

Bis(acetyl-acetonato-κO,O')(methanol-κO)(thio-cyanato-κN)manganese(III).

Project description:In the title complex, [Mn(C(5)H(7)O(2))(2)(NCS)(CH(4)O)], the Mn(III) atom has a slightly distorted octa-hedral coordination formed by five O atoms and one N atom. The equatorial positions are occupied by four O atoms of two acetyl-acetonate ligands, while the axial positions are occupied by the N atom of the thio-cyanate anion and the O atom of the methanol mol-ecule. In the crystal structure, complex mol-ecules are linked by an inter-molecular O-H⋯S hydrogen bond, forming a chain running along [101].

(Acetyl-acetonato-κO,O')-aqua-[salicyl-aldehyde nicotinoylhydrazonato(2-)-κO,N,O']manganese(III).

Project description:The Mn(III) atom in the title complex, [Mn(C(13)H(9)N(3)O(2))(C(5)H(7)O(2))(H(2)O)], is coordinated by three donors from a dianionic ligand, salicylaldehyde nicotylhydrazone, two O atoms from an acetyl-acetonate anion and a water mol-ecule in a distorted octa-hedral geometry. There is an extended two-dimensional supra-molecular motif resulting from O-H⋯N hydrogen bonds between the coordinated water mol-ecule and a hydrazine N or pyridine N atom, and from C-H⋯O hydrogen bonds between a CH group and the phenolate O atom.

1,3-Di-3-pyridyl-2,3-dihydro-1H-naphth[1,2-e][1,3]oxazine.

Project description:In the crystal structure of the title compound, C(22)H(17)N(3)O, the oxazine ring has a half-chair conformation. The dihedral angles between the best least-squares plane through the pyridine rings and the planar part (O-C-C-C-N) of the oxazine ring are 72.14 (6) and 35.44 (7)°, the smaller angle involving the pyridine ring adjacent to the oxazine O atom. The mol-ecule has two stereogenic centers at the oxazine carbons, RS and SR. The crystal packing reveals that symmetry-related mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds to form chains parallel to the b axis.
