(Pyridine-2-aldoximato-?(2) N,N')bis-[2-(pyridin-2-yl)phenyl-?(2) C (1),N]iridium(III).

ABSTRACT: In the title complex, [Ir(C11H8N)2(C6H5N2O)], the octa-hedrally coordinated Ir(III) atom is bonded to two 2-(pyridin-2-yl)phenyl ligands, through two phenyl C and two pydidine N atoms, and to one pyridine-2-aldoxime ligand through a pyridine N and an oxime N atom. The oxime O atom of the aldoxime unit forms inter-molecular C-H?O hydrogen bonds, which result in a two-dimensional hydrogen-bonded polymeric network parallel to (100). C-H?? inter-actions are also observed.

Project description:The title cyclo-metalated distorted octa-hedral iridium complex, [Ir(C11H6F2N)2(C12H12N2O2)]PF6, exhibits elongated Ir-N bonds to the dimeth-oxy bi-pyridine ligand [2.128 (3) and 2.136 (3) Å] where these nitro-gen atoms are trans to the Ir-C bonds of the two cyclo-metalating di-fluoro-phenyl-pyridine ligands. The angles between the mean planes of the phenyl and pyridyl fragments within the individual ligands range from 3.5 (2) to 11.4 (2)° to deviate slightly from coplanarity.

(4-Chloro-acetanilido-κ(2)N,O)bis-[2-(pyridin-2-yl)phenyl-κ(2)C(1),N]iridium(III).

Project description:In the neutral mononuclear iridium(III) title compound, [Ir(C(8)H(7)ClNO)(C(11)H(8)N)(2)], the Ir(III) atom adopts an octa-hedral geometry, and is coordinated by two 2-phenyl-pyridyl ligands and one anionic 4-chloro-acetanilide ligand. The 2-phenyl-pyridyl ligands are arranged in a cis-C,C' and cis-N,N' fashion. Each 2-phenyl-pyridyl ligand forms a five-membered ring with the Ir(III) atom. The 2-phenyl-pyridyl planes are perpendicular to each other [dihedral angle = 89.9 (1)°]. The Ir-C and Ir-N bond lengths are comparable to those reported for related iridium(III) 2-phenyl-pyridyl complexes. The remaining two coordination sites are occupied by the amidate N and O atoms, which form a four-membered ring with the iridium atom (Ir-N-C-O). The amidate plane is nearly perpendicular to both 2-phenyl-pyridyl ligands [dihedral angles = 87.8 (2) and 88.3 (2)°].

Project description:The structure of the title salt complex, [Fe(C(12)H(8)N(3)O(2))(2)]ClO(4)·H(2)O, contains one Fe(III) cation, two N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidate (bpca(-)) anions, one perchlorate anion and one water mol-ecule.
