The two K(+) ions lie on crystallographic inversion centers. The Eu-O bond distances are in the range 2.294?(5)-2.413?(5)?Å. The crystal used was a non-merohedral twin, the ratio of the twin domains being 0.5236?(5):0.4764?(5).

In the crystal structure of the title complex, K[Eu(C(5)HF(6)O(2))(2)(C(10)H(6)F(3)O(2))(2)], the Eu(III) ion is in a slightly distorted square-anti-prismatic coordination geometry which is defined by eight O atoms of the anionic β-diketone ligands. The two K(+) ions lie on crystallographic inversion centers. The Eu-O bond distances are in the range 2.294 (5)-2.413 (5) Å. The crystal used was a non-merohedral twin, the ratio of the twin domains being 0.5236 (5):0.4764 (5). ...[more]

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.

Tris(1,1,1,5,5,5-hexa-fluoro-2,4-pentane-dionato-?O,O')molybdenum(III).

Project description:In the title compound, [Mo(C(5)HF(6)O(2))(3)], the unit cell is built up by three independent Mo(III) atoms located on two different threefold axes. The three independent mol-ecules are roughly identical and each Mo(III) atom is surrounded by three chelating hexa-fluoro-acetonate ligands in a three-bladed propeller-like arrangement, as observed in related compounds with acetyl-acetonate-type ligands. The structure of the title compound is very similar to the trigonal form of the Cr(III) analogue. However, the latter crystallizes in a higher-symmetry space group, Pc1. Both crystals are twinned by merohedry with the same twin law (0/010/00) in reciprocal space, but the symmetry of the Laue group in which it operates is different, to m for the title complex, and m to 6/mmm for the Cr(III) complex.

trans-Bis(1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato-κO,O')bis-(4-methyl-1,2,3-selenadiazole-κN)copper(II).

Project description:In the title compound, [Cu(C(5)HF(6)O(2))(2)(C(3)H(4)N(2)Se)(2)], the Cu(II) atom (site symmetry ) is coordinated by two O,O'-bidentate 1,1,1,5,5,5-hexa-fluoro-2,4-penta-nedione (hp) ligands and two 4-methyl-1,2,3-selenadiazole mol-ecules, resulting in a slightly distorted trans-CuN(2)O(4) octa-hedral geometry in which the cis angles deviate by less than 3° from 90°. The selenadiazole plane is canted at 73.13 (17)° to the square plane defined by the penta-nedionate O atoms. The F atoms of one of the hp ligands are disordered over two sets of sites in a 0.66 (3):0.34 (3) ratio. There are no significant inter-molecular inter-actions in the crystal.

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].

Project description:In the title compound, [Co(C(5)HF(6)O(2))(2)(C(9)H(8)N(2))], the Co(II) centre exhibits a pseudooctahedral coordination geometry, comprising two N-atom donors from the bidentate amino-quinoline ligand and four O-atom donor atoms from two bidentate chelating 1,1,1,5,5,5-hexafluoropentane-2,4-dionate ligands. In the crystal, molecules are linked via pairs of N-H?O hydrogen bonds, forming inversion dimers. These dimers are further connected through ?-? interactions between neighbouring quinoline rings [centroid-centroid distance = 3.472?(2)?Å], and stack along the c axis.

(1-Ferrocenyl-4,4,4-trifluoro-butane-1,3-dionato-κO,O)bis-(triphenyl-phosphane)copper(I).

Project description:In the title mononuclear coordination complex, [CuFe(C(5)H(5))(C(9)H(5)F(3)O(2))(C(18)H(15)P)(2)], the Cu(I) ion is coordinated by the chelating β-diketonate 1-ferrocenyl-4,4,4-trifluoro-butane-1,3-dione ligand through two O atoms and the two datively bonded triphenyl-phosphane ligands resulting in a distorted tetra-hedral coordination sphere. The Cu(I) ion, together with its chelating butane-1,3-dione group, is mutually coplanar [greatest displacement of an atom from this plane = 0.037 (1) Å], and the Cu(I) ion lies slightly above [0.013 (1) Å] the plane. The overall geometry, including the bond distances and angles within the complex, corresponds to those of other reported copper(I) β-diketon-ates featuring organic groups at the β-diketonate ligand.

A 2:1 cocrystal of the cis and trans isomers of bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κO,O']bis-(4-phenyl-pyridine N-oxide-κO)copper(II).

Project description:The title compound is a co-crystal of the cis and trans isomers, namely cis-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis-(4-phenyl-pyridine N-oxide-κO)copper(II)-trans-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis(4-phenyl-pyridine N-oxide-κO)copper(II) (2/1), [Cu(C(5)HF(6)O(2))(2)(C(11)H(9)NO)(2)]. In both isomers, the coordination geometry of the Cu(2+) atom is octa-hedral, exhibiting typical Jahn-Teller distortion. The metal atom of the trans isomer is located on an inversion centre. In the cis isomer, the phenyl ring in one 4-phenyl-pyridine N-oxide ligand is disordered over two orientations in a 1:1 ratio. In the crystal, weak inter-molecular C-H⋯F and C-H⋯O contacts establish connections between the cis and trans isomers.
