In the title compound, C(22)H(16)F(3)NO(7)S, the two benzene rings are almost perpendicular, the dihedral angle between their mean planes being 87.1 (1)°. The terminal O atom of the benzoate moiety is disordered over two positions with site occupancies of 0.244 (15) and 0.756 (15). The crystal structure is stablized by two types of weak inter-molecular C-H⋯O hydrogen bonds.
IN THE TITLE TRICHODERMIN COMPOUND (SYSTEMATIC NAME: 12,13-ep-oxy-trichothec-9-en-4β-yl 4-fluoro-benzoate), C(22)H(25)FO(4), the five-membered ring displays an envelope conformation, whereas the two six-membered rings show the different conformations, viz. chair and half-chair. As for the seven-membered ring, the dihedral angle between the mean planes formed by the four C atoms of the envelope ...
P, Vm, T data have been measured for the nematic and isotropic phases of 3-cyanobenzyl 2,5-bis (4-n-octyloxybenzoyloxy)benzoate between 273 and 423 K and up to 250 MPa. The volume changes accompanying the crystal nematic and nematic isotropic transitions have been determined. The corresponding enthalpy changes have been calculated using the Clausius-Clapeyron equation. The p, Vm, T data enable ...
The mol-ecule of the title compound, C16H13BrO3, is built of two approximately planar fragments, viz. 3-bromo-benzoate [maximum deviation = 0.055 (2) Å and 2-oxo-2-p-tolyl-ethyl [maximum deviation = 0.042 (2) Å], inclined by 46.51 (7)°. In the crystal, weak C-H⋯O hydrogen bonds and Br⋯Br contacts [3.6491 (7) Å] connect the mol-ecules into infinite layers parallel to (-221).
The conformation of the C=O bond in the title compound, C(14)H(11)ClO(2), is anti to the Cl atom, similar to what was observed in 2-methyl-phenyl 4-methyl-benzoate. The dihedral angle between the two aromatic rings is 59.36 (7)°.
The title dimeric complex, [Eu(2)(C(7)H(5)O(2))(6)(C(3)H(7)NO)(2)(H(2)O)(2)], is centrosymmetric, implying that pairs of equivalent Eu(3+) ions and ligands lie trans to each other and that the two Eu(3+) ions have exactly the same coordination environment. Each Eu(3+) ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylf...
In the title compound, [Cu(2)(C(7)H(5)O(2))(4)(C(10)H(9)N)(2)], the paddle-wheel-type dinuclear complex is constructed by four bridging benzoate groups and two terminal 6-methyl-quinoline ligands. The asymmetric unit contains one-half of the whole mol-ecule, and there is an inversion center at the mid-point of the Cu⋯Cu bond. The octa-hedral coordination of each Cu atom, with four O atoms in th...
In the title salt, C(5)H(8)N(3) (+)·C(7)H(6)NO(2) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The proton-ated N atom and one of the two N atoms of the 2-amino groups are hydrogen bonded to the 3-amino-benzoate anion through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The carboxyl-ate mean plane of the 3-amino-benzoate anion is twisted by ...
