In the title compound, [Ni(C13H18NO3)2(C12H8N2)], the NiII cation shows a distorted octa-hedral coordination environment. It is formed by two N atoms from the phenanthroline ligand, as well as two N and two O atoms belonging to two 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noate ligands. Complex mol-ecules are connected into layers propagating along the ab plane via hydrogen bonds formed by ...

In the title compound, C(17)H(23)NO(4)S, the penta-diene group adopts a planar conformation, with an r.m.s. deviation of 0.0410 (14) Å. The phenyl ring makes a dihedral angle of 85.73 (11)° with the penta-diene group, while the penta-diene group makes dihedral angles of 11.38 (11) and 14.08 (10)°, respectively, with the amino and ester groups. In the crystal, molecules are linked via pairs of C...

The title compound, [Mo(C(36)H(29)P)(CO)(3)], contains an Mo(0) atom with a typical piano-stool coordination defined by the phospho-nium cyclo-penta-dienylide ligand η(5)-1-(methyl-diphenyl-phosphanium-yl)-2,3,5-triphenyl-2,4-cyclo-penta-dien-1-yl and by three carbonyl groups. The distance between the Mo(0) atom and the cyclo-penta-dienyl ring is 2.0616 (13) Å.

In the title compound, [Fe(C5H5)(C20H13N2O2)], the substituted cyclo-penta-dienyl ring and quinoline system are approximately coplanar, making a dihedral angle of 5.18 (6)°, while the dihedral angle between the quinoline system and the benzene ring is 28.45 (8)°. There is high thermal motion in the free cyclo-penta-dienyl ring compared with the substituted cyclo-penta-dienyl ring. The conformat...

The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom. Each Ti atom is bonded to a η(5)-penta-methyl-cyclo-penta-dienyl ring, two (penta-fluoro-phen-yl)methano-late anions and to the bridging O atom. The environment around each Ti atom can be considered as a distorted tetra-hedron.

Five polychlorinated biphenyl (PCB)-degrading bacteria were tested for the ability to differentiate between the enantiomers of four atropisomeric PCB congeners (2,2',3,6-tetra-CB; 2,2',3,3',6-penta-CB; 2,2',3,4',6-penta-CB; and 2,2',3,5',6-penta-CB) after growth in the presence of tryptone-soytone, biphenyl, carvone, or cymene. Enantioselectivity was shown to vary with respect to strain, congen...

We study cluster algebras for some all-loop Feynman integrals, including box-ladder, penta-box-ladder, and (seven-point) double-penta-ladder integrals. In addition to the well-known box ladder whose symbol alphabet is $D_2\simeq A_1^2$, we show that penta-box has an of $D_3\simeq A_3$ provide strong evidence double-penta can be identified with a $D_4$ algebra. relate letters ${\bf u}$ variables...

BACKGROUND The present study was undertaken to examine the immunological effects of pentabrominated diphenyl ether (penta-BDE) and decabrominated diphenyl ether (deca-BDE) on the immune system of the dams and the developmental immune system of the offsprings. METHODS In this study, mated female C57BL/6J mice were orally administered penta-BDE, deca-BDE or corn oil for 5 weeks, from gestationa...
