Binuclear rhodium(II) complexes [Rh(2)Cl(2)(mu-OOCR)(2)(N-N)(2)] {R = H, Me; N-N = 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen)} and [Rh(2)(mu-OOCR)(2)(N-N)(2)(H(2)O)(2)](RCOO)(2) (R = Me, Et;) have been synthesized and their structure and properties have been studied by electronic, IR and (1)H NMR spectroscopy. Antibacterial activity of these complexes against Escherichia coli and Staphyl...

In the mononuclear title compound, [Ni(C(10)H(9)N(4)O(2)S)(2)(C(12)H(8)N(2))], the Ni(II) atom has a distorted octa-hedral coordination geometry comprising four N atoms from two 4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidate ligands and two N atoms from a 1,10-phenanthroline ligand. In the crystal, mol-ecules are connected into a three-dimensional supra-molecular network via N-H⋯O hydrogen bon...

Reactions of equemolar amounts of lead (II) nitrate and 2,2'- bipyridine o r l , 10- phenanthroline in aqueous methanolicsolution yield crystals of Pb (bipy)(H O)(NO ) (1) or Pb (phen) (H O) (NO ) (2) respectively. Their structures were determined by X-ray crystallography. The method and structure determination is described

Two enzymes, tryptophan transaminase and indolepyruvate C-methyltransferase, which are active in the initial steps of the biosynthetic pathway of the antibiotic indolmycin, have been detected and partially purified from cell-free extracts of Streptomyces griseus. The transaminase has been purified 3-fold by ammonium sulfate fractionation. At this stage of purification, it catalyzes the alpha-ke...

In the crystal structure of the title compound, [Zn(C(7)H(10)O(4))(C(12)H(8)N(2))(2)]·6H(2)O, the Zn(II) atom is coordinated by two carboxyl-ate O atoms of a mono-bidentate chelating pimelate anion (pimelic acid is hepta-nedioic acid) and four N atoms of two phenanthroline ligands, forming a considerably distorted octa-hedral ZnN(4)O(2) coordination geometry. The complexes are assembled into a ...

The polymeric title compound, [Cu(C(6)H(2)O(5))(C(12)H(8)N(2))(C(5)H(10)N(2)O)](n), is composed of an infinite chain formed along [100] by linking the (1,3-dimethyl-imidazolin-2-one)(1,10-phenanthroline)copper(II) units with two O atoms of two carboxyl-ate groups of the furan-2,5-dicarboxyl-ate ligand. The Cu(II) atom, which lies on a twofold rotation axis, displays a square-pyramidal coordinat...

In the title mol-ecule, C(24)H(16)N(4)O·H(2)O, the benzene ring of the 1,10-phenanthroline group and that of the 2-phenyl-pyridine group are respectively twisted by 67.9 (1) and 15.3 (3)° from the carbamoyl group defined by the plane of the O=C-N group of atoms. The water mol-ecule is hydrogen bonded to one of the phenanthroline N atoms. In the crystal structure, significant π-π stacking inter-...

In the title complex, [Y(2)(C(5)H(6)O(4))(3)(C(12)H(8)N(2))(2)](n), three glutarate groups and two 1,10-phenanthroline mol-ecules surround the two Y(III) ions. Both Y(III) ions are coordinated by two N atoms from the 1,10-phenanthroline, seven O atoms from five glutarate groups in a distorted tricapped trigonal-prismatic geometry. The Y(III) ions are bridged by glutarate ligands in three modes,...
