In the title compound, [ReBr(C(12)H(9)ClN(2))(CO)(3)], the Re(I) atom has a distorted octa-hedral configuration with the three carbonyl ligands showing a facial arrangement. The main distortion of the octa-hedron is due to a small bite angle of the chelating bidentate diimine ligand [N-Re-N = 75.3 (3)°].

In the title compound, [CoCl(2)(C(8)H(7)ClN)(C(3)H(9)P)(2)], the Co atom displays an octa-hedral coordination, with two cis Cl atoms perpendicular to two trans trimethyl-phosphine ligands as well as trans to the bidentate 3-chloro-2-methyl-imino-phenyl ligand.

A ruthenium benzylidene complex with a neutral bidentate N-heterocyclic carbene was prepared and evaluated in ring-closing metathesis of diallyl substrates. Reaction with AgPF6 to generate a four-coordinate complex produced an unexpected dicationic ruthenium benzyl degradation product through nucleophilic attack of the NHC ligand on the benzylidene carbon.

The anisotropic correlation between buckled dimers on Si(100) was investigated by scanning tunneling microscopy. A bidentate ligand molecule was used to pin two neighboring dimers at 300 K. The chemically pinned dimer induces antiferromagnetic interaction along the dimer rows. Observed results agree well with Monte-Carlo simulations semi-quantitatively.

In the title complex, [Cu(C(12)H(15)Cl(2)N(2)O)(2)], the Cu(II) ion is coordinated by one N,O-bidentate and one N,N',O-tridentate Schiff base ligand, resulting in a distorted CuN(3)O(2) square-based pyramidal coordination for the metal ion, with the O atoms lying trans to each other in the basal plane.

Copper (II) complexes with commercial antibiotics, amoxicillin (AMX), azithromycin (AZT) and ciprofloxacin (CFL) were synthesized isolated as solids. Structures of the products determined by FTIR spectroscopy. Antibacterial activities on reference bacterial strains from ATCC collection diffusion technique. The results show that AMX CFL coordinate Cu ion bidentate O-donor ligand. AZT coordinates...

The title compound, [Au(2)Cl(2)(C(28)H(30)N(2)P(2))]·2C(4)H(8)O, was synthesized from a bidentate phosphine ligand complexed to two linear gold(I) chloride moieties. The Au(I) atom is in an almost linear coordination with a P-Au-Cl angle of 179.22 (4)°. The complex molecules reside on a twofold rotation axis.

In the title complex, [Cu(C(9)H(7)N(2)O(2)S)(2)], the Cu(II) ion, located on an inversion center, adopts an N(2)O(2) square-planar coord-ination. The 2-(5-methyl-sulfanyl-1,3,4-oxadiazol-2-yl)phenolate ligand is chelated to the central Cu(II) ion in an N,O-bidentate manner.

In the title coordination polymer, [Cu(NCS)(2)(C(12)H(8)N(2))](n), the Cu(II) atom is situated on a twofold rotation axis and is coordinated by two N atoms from the bidentate 1,10-phenanthroline ligand and four thio-cyanate groups to confer a CuN(4)S(2) octa-hedral geometry and resulting in a layer structure extending parallel to (100).

A boradiazaindacene (BODIPY) derivative containing a simple NO bidentate ligand shows a Cu(2+)-selective fluorescence in aqueous media. This is promoted via a coordination of Cu(2+) followed by oxidative dehydrogenation of an amine moiety, leading to a formation of a fluorescent Cu(+)-Schiff base complex.
