From the spectra (Figure 3(a)), [DELTA] = 216 [cm.sup.-1] indicating that the formate group is bound with the titanium precursor by a bidentate bridging mode; the proposed scheme I is shown in Figure 4.
Caption: Figure 9: Schematic representation of possible modes of binding of glutarate with the passive film: (a) bidentate chelating at both ends, (b) bidentate bridging at both ends, and (c) bidentate chelating-monodentate.
The results obtained from the experimental data show the probable existence of two bidentate complexes on the surface.
The specified structure of the one is undoubtedly linked with bidentate character of OPD that will be confirmed during IR-spectroscopic researches and it will be shown below.
We obtained superhydrophobic Al surfaces via dodecylphosphonic acid [DDPA, [CH.sub.3][([CH.sub.2]).sub.12]P(O) [(OH).sub.2]] monolayer derivatization and found that DDPA was connected to Al mainly by bidentate P-O-Al bonds.

Nectary of one dorsal tridentate or tetradentate gland, 3 x 2.5 mm, less often two dorsal bidentate glands, 2 x 1 mm each.
The final section explores the oxidation of alcohols and amines to carbonyl compounds and imines catalyzed by well-defined transition metal complexes bearing bidentate and miscellaneous chelating ligands, recent progress in reducing polar carbon-heteroatom unsaturated bonds, and carbon-carbon bond-forming reactions via hydrogen transfer.
The catalyst is based on a transition metal complex containing a [pi]-allyl ([xi]3-allyl) ligand and a bidentate [beta]-ketoimine ligand as a main catalyst, and a norbornene compound in which a methylene chain is introduced between a norbornene skeleton and an ester group.
The unidentate and bidentate nitrates show the frequency separation of 115 and 186 cm-1 respectively while the combination bands (1+4) for free nitrate ion appear in the regions of 1800-1700 cm-1 [3031].
