?(2)-Acetone-diacetone[?(3)-tris-(trifluoro-meth-yl)methano-lato]bis-[?(2)-tris-(trifluoro-meth-yl)methano-lato]trilithium.

ABSTRACT: The title compound, [Li(3)(C(4)F(9)O)(3)(C(3)H(6)O)(3)], features an open Li/O cube with an Li ion missing at one corner. Three of the four bridging O atoms of the cube carry a fluorinated tert-butyl residue, whereas the fourth is part of an acetone mol-ecule. Two of the Li atoms are further bonded to a non-bridging acetone mol-ecule. Two of the lithium ion coordination geometries are very distorted LiO(4) tetra-hedra; the third could be described as a very distorted LiO(3) T-shape with two distant F-atom neighbours. The Li?Li contact distances for the three-coordinate Li(+) ion [2.608?(14) and 2.631?(12)?Å] are much shorter that the contact distance [2.940?(13)?Å] between the tetra-hedrally coordinated species.

Project description:In the title compound, C(24)H(9)F(18)OP, an intra-molecular C-H⋯O short contact generates a five-membered ring, producing an S(5) ring motif. The dihedral angles between the benzene rings are 57.68 (10), 77.80 (11) and 79.48 (10)°. Each of the six trifluoro-methyl substituents shows rotational disorder over two positions with refined site-occupany ratios of 0.64 (3)/0.36 (3), 0.649 (14)/0.351 (14), 0.52 (2)/0.48 (2), 0.545 (16)/0.455 (16), 0.774 (9)/0.226 (9) and 0.63 (5)/0.37 (5). The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯F inter-actions.

Bis[tris-(3,5-dimethyl-1H-pyrazol-1-yl-κN(2))meth-yl]sodium trifluoro-methane-sulfonate.

Project description:In the title salt, [Na(C(16)H(22)N(6))(2)]CF(3)SO(3), the Na(+) cation is coordinated by six N atoms from two tridentate tris-(3,5-dimethyl-pyrazol-1-yl)methane ligands in a distorted octa-hedral geometry. The Na-N distances range from 2.427 (3) to 2.507 (3) Å, intra-ligand N-Na-N angles range from 74.71 (8) to 79.31 (9)°, and adjacent inter-ligand N-Na-N angles range between 100.42 (9) and 104.97 (9)°. The structure is twinned by inversion [occupancy factors = 0.50 (9)] and the trifluoro-methane-sulfonate anion is disordered, with two end-over-end orientations of unequal occupancy [0.781 (3) and 0.219 (3)].

Crystal structure of bis-[?-meth-oxy(pyridin-2-yl)methano-lato-?(3) N,O:O]bis[chlorido-copper(II)].

Project description:The racemic title compound, [Cu2(C7H8NO2)2Cl2], is composed of dinuclear mol-ecules in which meth-oxy(pyridin-2-yl)methano-late ligands bridge two symmetry-related Cu(II) ions. Each Cu(II) ion is coordinated in a square-planar geometry by one Cl atom, the N and O atoms of the bidentate ligand and the bridging O atom of the centrosymmetrically related bidentate ligand. The separation between the two Cu(II) atoms is 3.005?(1)?Å. In the crystal, non-classical C-H?O hydrogen bonds, weak ?-? stacking [centroid-centroid distance = 4.073?(1)?Å] and weak electrostatic Cu?Cl inter-actions [3.023?(1)?Å] link the dinuclear mol-ecules into chains running parallel to the b axis. These chains are further connected by weak C-H?Cl hydrogen bonds directed approximately along the a axis, forming a three-dimensional supra-molecular network.

2,6-Bis(trifluoro-meth-yl)benzoic acid.

Project description:The title compound, C(9)H(4)F(6)O(2), contains two mol-ecules in the asymmetric unit, one of which exhibits disorder in both of its trifluoro-methyl groups. The dihedral angles between the benzene ring and the carboxyl group are 71.5 (2) and 99.3 (2)° in the two independent mol-ecules. The compound exhibits a catemeric structure resulting from inter-molecular O-H⋯O hydrogen bonding between the carboxyl groups.

1,2-Bis{bis-[4-(trifluoro-meth-yl)phen-yl]phosphino}ethane.

Project description:Crystals of the title compound, C(30)H(20)F(12)P(2) or R(2)PCH(2)CH(2)PR(2) (R = 4-C(6)H(4)CF(3)), were inadvertently prepared while attempting to recrystallize a crude sample of trans-Re(Cl)(N(2))(R(2)PCH(2)CH(2)PR(2))(2) from diethyl ether. The molecule lies on a center of inversion. One of the rings lies approximately in the P-C-C-P plane; the dihedral angle is 174.53°.The other ring is not quite perpendicular; the dihedral angle is 71.1°. The compound is isostructural with the R = Ph, 4-C(6)H(4)CH(3) and 4-C(6)H(4)CH(2)CH(3) analogues. It is well known that the basicity of phosphines and diphosphines can be altered by changing the electron-donating ability of R; however, the structural parameters for the title compound do not significantly differ from those of the aforementioned substituted-phenyl compounds.

1,1-Bis[4-(trifluoro-meth-yl)phen-yl]germetane.

Project description:The inter-nal C-Ge-C bond angle in the germacyclo-butane ring of the title compound, C(17)H(14)F(6)Ge or [Ge(C(3)H(6))(C(7)H(4)F(3))(2)], is 77.8 (3)°. The -CF(3) groups display rotational disorder [occupancies 0.604 (14):0.396 (14) and 0.410 (6):0.411 (6):0.179 (3)] and the germacyclo-butane ring also shows disorder [occupancies 0.604 (14):0.396 (14)].

Bis{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato-κO,O}tris-(nitrato-κO,O')methano-lsamarium(III).

Project description:The asymmetric unit of the title compound, [Sm(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], contains two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (HL) ligands, three nitrate ions and one methanol mol-ecule that binds to the nine-coordinate samarium(III) ion via its O atoms. The HL ligands chelate with a strong Sm-O(deprotonated phenolic) bond and a weak Sm-O(meth-oxy) contact. The latter can be inter-preted as the apices of the bicapped square-anti-prismatic Sm(III)O(9) polyhedron. The Schiff base ligands are in a zwitterionic state with the phenolic H atom transferred to the imine N atom. O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds lend stability to the structure. One O atom of one nitrate group is equally disordered over two positions.

Tris(tetra-hydro-furan-?O)tris-[tris-(thio-phen-2-yl)methano-lato-?O]terbium(III) tetra-hydro-furan monosolvate.

Project description:In the mononuclear title compound, [Tb(C(13)H(9)OS(3))(3)(C(4)H(8)O)(3)]·C(4)H(8)O, the lanthanide cation is located on a threefold rotation axis and is surrounded by electron-rich ligands in an approximately octa-hedral geometry. One of the thienyl groups and the bound THF are disordered with 0.5:0.5 occupancy. The free THF is disordered around the threefold axis.

Bis[(2-pyrid-yl)(2-pyridyl-amino)-methano-lato]manganese(III) nitrate.

Project description:The Mn(III) atom in the title complex, [Mn(C(11)H(10)N(3)O)(2)]NO(3), is coordinated by the two tridentate (2-pyrid-yl)(2-pyridyl-amino)-methano-late ligands, forming a six-coordinate environment. The four pyridyl N atoms constitute the equatorial plane on which the manganese(III) ion lies; the coordination plane suffers a slight distortion as indicated by the average plane deviation of 0.058?Å. The methano-late O atoms occupy the axial positions. The coordination geometry is thus octa-hedral. In the title compound, the cations are linked by nitrate anions via N-H?O hydrogen bonds to form one-dimensional chains. Moreover, the one-dimensional structure is stabilized by inter-molecular edge-to-face aromatic ?-? inter-actions with a center-of-inversion at a distance of ca 4.634?Å.
