This paper reports the synthesis of the first bis(amino)borate ligand, [Ph(2)B(CH(2)NMe(2))(2)](-), an anionic equivalent of tertiary diamines. Anionic [Ph(2)B(CH(2)NMe(2))(2)] is an excellent bidentate ligand auxiliary and is used to prepare a series of N-chelated, zwitterionic rhodium(I) complexes.

Treatment of Cu(AcO)(2) with D-penicillamine or L-cysteine in the presence of 2,2'-bipyridine afforded dicopper(II) complexes with a bis(bidentate-N,O) disulfide ligand, the formation mechanism of which was discussed on the basis of Cu(II)-thiolate interaction affected by an auxiliary ligand.

The mol-ecular structure of the title titanium(IV) half-sandwich complex, [Ti(η5-C10H15)(η4-C21H19N)(C12H10N)], shows a three-legged piano-stool geometry at the central TiIV atom, comprising of one penta-methyl-cyclo-penta-dienyl ligand, one bidentate ketimine ligand in an η4-coordination mode and one monodentate di-phenyl-amide ligand. Except for van der Waals forces, there are no significant ...

In the title compound, [Mn(C(2)N(3))(NO(3))(C(24)H(16)N(6))(H(2)O)], the central manganese(II) ion is hepta-coordinated to a tridentate 2,3,5,6-tetra-2-pyridylpyrazine ligand (tppz), a bidentate nitrate ligand, a terminal monodentate dicyanamide ligand (dca) and a water mol-ecule. The structure contains isolated neutral complexes, which are linked by O(water)-H⋯N hydrogen bonds generating chain...

In the title compound, [CuCl(2)(C(26)H(18)N(4))](n), the Cu(II) ion is four-coordinated by two N atoms from two 4,4'-bis-(benzo-imidazol-1-yl)biphenyl ligands and two chloride anions, in a slightly distorted tetra-hedral environment. The biphenyl ligand acts as a linear bidentate ligand, connecting the metal atoms into an infinite chain parallel to [101]. In the biphenyl ligand, the two benzene...

Ir catalysts supported by bidentate silyl ligands that contain P- or N-donors are shown to effect ortho borylations for a range of substituted aromatics. The substrate scope is broad, and the modular ligand synthesis allows for flexible catalyst design.

The effect of ligand structure on the cytotoxicity of cationic CdSe/ZnS quantum dots (QDs) was systematically investigated using mono- and bidentate ligands. Monothiol-functionalized QDs are more cytotoxic than dithiol-functionalized QDs.

Use of a bulky bidentate bis(NHC) ligand allows isolation of a stable cationic methylpalladium carbonyl complex that undergoes clean carbonylation to an acyl complex under excess CO, modeling a key step in CO/alkene copolymerization.

Facile hydrolysis of a phosphodiester promoted by a dicopper bis(mu-hydroxo) complex containing a new biphenyl appended N-bidentate ligand led to the isolation of the first example of hexameric copper pyrophosphate through 'in situ self assembly'.
