in a search for new leads towards potent antimicrobial agents, an array of novel (2e)-ethyl-2-(2-(2,4-dinitrophenyl)hydrazono)-4-(naphthalen-2-yl)-6-arylcyclohex-3-ene carboxylates 17-24 were synthesized and characterized through their melting point, elemental analysis, ms, ft-ir, one-dimensional nmr (1h, d2o exchanged 1h and 13c), two dimensional homocor and hsqc spectroscopic data. in-vitro m...

The Sn(IV) atom in the title salt, [N(CH(3))(3)(C(6)H(5))](2)[SnBr(4)(C(6)H(4)Cl)(2)], exists in a distorted all-trans SnC(2)Br(4) octa-hedral geometry. The Sn(IV) atom lies on a center of inversion. Weak inter-molecular C-H⋯Br hydrogen bonding is observed between trimethyl-phenyl-ammonium cations and the Sn complex anion in the crystal structure.

In the title compound, [Ni(C(5)H(7)O(2))(2)(C(12)H(16)N(3)O(2))], the Ni(II) cation is hexa-coordinated by four O and two N atoms, showing a slightly distorted octa-hedral geometry. The Ni(II) cation lies on an inversion centre, as a consequence of which the asymmetric unit comprises one half-mol-ecule. The four O atoms belonging to two pentane-2,4-dionate ligands lie in the equatorial plane an...

lysine metabolism has been measured in rats fed a diet low in trimethyl-lysine and carnitine (Davis & Hoppel, 1983, 1986). Under these steady-state conditions, the total body trimethyl-lysine content is similar to the total body carnitine content. The tissue distribution of peptide-linked and free trimethyl-lysine shows that approximately 68% of the total trimethyl-lysine is present in skeletal...

Dedicated to Professor Hartmut Bärnighausen on the occasion of his 70th birthday Z. Naturforsch. 58b, 299Ð304 (2003); received December 17, 2002 The reaction of Cp*V(CO)4 (1) with molecular oxygen in diluted pentane solution leads to a tetrameric dioxide, [Cp*V(O)(μ-O)]4 (2), which is a precursor of the octanuclear aggregate Cp*6V8O17 (3). The molecular structures of 1 and 2 have been determine...

In the title compound, C(7)H(14)O(2), co-operative eight-membered homodromic rings of O-H⋯O hydrogen bonds connect the mol-ecules into strands along [100]. According to graph-set analysis, the descriptor of these cycles is R(4) (4)(8). The cyclo-pentane-ring adopts an envelope conformation ((C4)E).

The mol-ecule of the title compound, C(17)H(16)Br(2)N(2)O(2), lies on a twofold axis that passes through the middle atom of the three-atom trimethyl-ene unit. The two aromatic rings are aligned at an angle of 76.02 (4)°.
