Bis(pentane-2,4-dionato-κO,O')bis-[4,4,5,5-tetra-methyl-2-(4-pyridyl)-imidazoline-1-oxyl 3-oxide-κN]manganese(II).

ABSTRACT: The title compound, [Mn(C(5)H(7)O(2))(2)(C(12)H(16)N(3)O(2))(2)], is isostructural with its Ni(II)-containing analogue [Hao, Mu & Kong (2008 ▶). Acta Cryst. E64, m957]. The asymmetric unit comprises one-half of the mol-ecule and the Mn(II) ion is located on an inversion centre. The coordination geometry around the Mn(II) ion is slightly distorted octa-hedral, comprised of four O and two N atoms, in which the four O atoms in the equatorial plane come from two pentane-2,4-dionate ligands and the two N atoms in the axial coordination sites from 4,4,5,5-tetra-methyl-2-(4-pyrid-yl)imidazoline-1-oxyl 3-oxide.

Diazido-bis[4,4,5,5-tetra-methyl-2-(1,3-thia-zol-2-yl)-2-imidazoline-1-oxyl-3-oxide-κO,N]manganese(II).

Project description:In the crystal structure of the title compound, [Mn(N(3))(2)(C(10)H(14)N(3)O(2)S)(2)], the Mn(II) atom exhibits a roughly octa-hedral coordination geometry. The Mn(II) atom lies on an inversion centre, thus the asymmetric unit comprises one half-mol-ecule. The metal center is six-coordinated by two azide anions and by two chelating 4,4,5,5-tetra-methyl-2-(1,3-thia-zol-2-yl)-2-imidazoline-1-oxyl-3-oxide nitronyl nitroxide radical ligands, leading to two six-membered chelate rings.

Bis[μ-pentane-2,4-dionato(1-)]bis-{aqua-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)]cobalt(II)}.

Project description:The title complex, [Co(2)(C(5)HF(6)O(2))(2)(C(5)H(7)O(2))(2)(H(2)O)(2)], is centrosymmetric with a crystallographic inversion center in the middle of the mol-ecule. The octa-hedrally coordinated Co(II) atoms are bridged by two chelating acetyl-acetonate (acac) ligands and two more electron-poor 1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato (hfac) ligands are bonded terminally in a solely chelating manner. The coordinated water mol-ecules form inter-molecular O-H⋯O hydrogen bonds with electron-rich acac O atoms of neighboring mol-ecules, leading to strings of mol-ecules along the a axis.

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].

Diaqua-bis-(benzoato-κO)bis-[4,4,5,5-tetra-methyl-2-(pyridin-4-yl-κN)imidazoline-1-oxyl 3-oxide]cobalt(II).

Project description:The title compound, [Co(C(7)H(5)O(2))(2)(C(12)H(16)N(3)O(2))(2)(H(2)O)(2)], was obtained from a conventional solvent evaporation method. The complex mol-ecule is centrosymmetric, so pairs of equivalent ligands lie trans to each other in a slightly distorted octa-hedral CoN(2)O(4) geometry. The Co(II) ion is coordinated by the pyridine N atoms from NITpPy ligands [NITpPy is 4,4,5,5-tetra-methyl-2-(pyridin-4-yl)imidazoline-1-oxyl 3-oxide), water O atoms and two monodentate benzoate O atoms. The complex mol-ecules are connected by O-H⋯O hydrogen bonds between water mol-ecules and benzoate ligands, forming chains parallel to [100]. π-π stacking inter-actions between the benzoate ligands with centroid-centroid distances of 3.752 (2) Å connect the chains into layers parallel to (10-1).

Tris(3-nitro-pentane-2,4-dionato-κO,O')-cobalt(III).

Project description:The structure of the title compound, [Co(C(5)H(6)NO(4))(3)], consists of a Co(III) ion octahedrally coordinated by three bidentate 3-nitro-pentane-2,4-dionate ligands. The complex was prepared via the nitration of tris-(2,4-penta-nedionato-κ(2)O,O')cobalt(III) with a solution of copper(II) nitrate in glacial acetic acid. The central C atom and the nitro group of one 3-nitro-pentane-2,4-dionate ligand are disordered over two positions with an occupancy ratio of 0.848 (4):0.152 (4). A second nitro group is also disordered over two orientations with an occupancy ratio of 0.892 (7):0.108 (7). Two of the ligand methyl groups form C-H⋯O inter-actions with two different nitro groups to form chains running along the c axis. Additional C-H⋯O inter-actions are found between ligand methyl groups and the cobalt-bound O atoms, also resulting in the formation of chains along the c axis.

One trifluoro-methyl group is rotationally disordered between two orientations in a 1:1 ratio.
