Therefore, the europium sorption mechanisms in titanium pyrophosphate result from the interaction of a [equivalent to]XO[H.sub.2.sup.+] surface site (pH < 3.3) and a [equivalent to]X[O.sup.-] surface site (pH > 3.3) with EuN[O.sub.3.sup.2+] and the formation of the inner-sphere bidentate surface complexes.
Shift values to the low-frequency area of valent asymmetric fluctuations bands of [v.sub.as](N[H.sub.2]) ([DELTA] 180 [cm.sup.-1]) and valent symmetric fluctuations of [v.sub.s](N[H.sub.2]) ([DELTA] 150 [cm.sup.-1]) along with noticeable low-frequency shift in the range of 1590.1610 [cm.sup.-1] allow to speak about bidentate character of OPD in complex of [Cd[(OPD).sub.2]][(B[F.sub.4]).sub.2].
We demonstrated in our former work that the bonding configuration of phosphorus in the phosphonate headgroups was mainly bidentate in the case of DDPA monolayer derivatization on Al surfaces, i.e., contribution of P-O in [O.sub.1s] peak was relatively stronger than that of P=0.

Furthermore on the basis of UV and IR spectral characterization it was deduced that the zirconium formed the complex with 5-hydroxy-4- keto system whereas molybdenum formed the complex through catechol moiety but in both the cases rutin coordinated in bidentate fashion through the oxygen atoms of rings because they are the most effective coordination centers [2616].
The main differences in these models of complexes compared to the type of complexes from the Sandler research team are the pyrazole and carboxylic units of interest that are incorporated into the bidentate or tridentate ligands coordinating to the metal through the nitrogen atoms.
Xanthates can form bidentate, monodentate, or network solids, showing a wide range of coordination behaviour [3-6].
Sung and Schneider [19] have reported that the urea microdomains in polyurethane foams are known to possess bidentate hydrogen bonding which is associated with a 1640 [cm.sup.-1] absorbance observed via FTIR.
PALEA 3.1-4.75 x 0.5-0.85 mm, oblong and bidentate 2n= 42.
The reaction product of FeS[O.sub.4], [H.sub.2][O.sub.2,] and N[H.sub.3] * [H.sub.2]O, Fe[(OH).sub.3] precipitate, was washed repeatedly in order to remove the sulfate ions, which could form the bridging bidentate structure (FeOS[O.sub.2]O Fe) on [alpha]-[Fe.sub.2][O.sub.3] particle surfaces to result in aggregation [43].
Nectary of two bidentate glands 2 X 2 mm each, basally dark colored.
palmyra for the present, because they possess the distinctively concave posterior metasternum, a small and bidentate posteromedial metasternal process, and a basally incised fore tibia, but have not designated them as paratypes because of the significant geographic distance separating the two populations, which suggests that the Pagan population may eventually prove to be a distinct species once additional material is available for a more detailed evaluation.
