Bidentate species conformers

Adsorption of HCOOH and COg has been used to create HCOO and CO3 groups on CeOx/Au(lll) surfaces. The orientation of the formate on the ceria nanoparticles supported on Au(lll) is likely to be near normal to the surface as a bidentate species in a chelating or bridge conformation. No preferred orientation was... 

In these complexes, identical or different metal centers are, generally, connected by two pyrazolate ligands coordinated in an exo-bidentate fashion. In most cases, the M(/t-pz )2M core exhibits a boat conformation. Doubly bridged pyrazolate complexes are usually dimeric however, in the last years some homo-(MMM) and heterotrinuclear (MM M) species containing the metallocycles M(n-pz )2M(ji-pz )2M and M(/t-pz )2M (/i-pz )2M were reported. 

Although capable of bidentate function to one metal, steric and conformational preferences generally seem to dictate that dioxane acts either as a unidentate ligand or that it bridges two different metals, as in (79). The compound MnCli dioxane, for which (79) is the proposed structure, is not affected by six hours in vacuum at 100 C Other known MnXj dioxane species include those defined by n = 1, for X = CIO4, NCS and NCSe, and n = 2 for X = Br and I, and some mixed aquo-ether compounds. ...
