of the six models of Ru-L bonds obtained from the optimized geometries at MP2, CCSD, PBE, and B3LYP using SBKJC VDZ basis set.
ii) H (6) of chitosan is linked with O (13) of AA with the bond distance
Steine (2002) showed a correlation between the vOH frequency and hydrogen bond distance
, where the frequencies shown by the zinc compound, 3500 [cm.
Each pair of adjacent spheres is bonded, and can stretch, bend, and twist by changing the bond distance
, bond angle, and torsion angle, respectively.

The bond distances
derived from more accurate X-ray data obtained by crystallographer T.
Despite the capacity to solve relatively complex organic structures such as fluorescein diacetate by direct methods, obtaining all the carbon and oxygen atoms in the molecule with bond distances
to within about 0.
All bond distances
are within the expected ranges, the two nitrogens of the hydrazide moiety adopt two different geometries as expected; the amide-type nitrogen (N2) is planar which optimised the resonance interaction with the carbonyl group (C7-O1), while the amino-like nitrogen (N3) is pyramidalised, a geometry that optimises both H-bond donor and H-bond acceptor properties of N3.
The difference in siting is attributed to the difference in Ge-O bond distances
and Ge- O-Al flexibility in comparison to those in aluminosilicates.
