Crystal engineering of new solid-state coordination architectures with bidentate
ligands and various transition metal ions, offers an exciting approach to the discovery of novel multi-dimensional arrays, which may possess functional properties.

In many instances, thiosemicarbazones act as a bidentate
ligand and bind to the metals through the sulfur and hydrazinic nitrogen atom.
The reason is probably that one B-X group is not able to stabilize the ion and the distance between two electron-withdrawing groups is too large (ca 4 A) to have preferred bidentate
interaction, so the most stable form left is the one with the proton placed between the middle-belt and the topmost boron in the case of 1:3:1 systems and between two middle-belt borons in the case of 1: 4: 1 clusters.

, falciger blades; proximal tooth sligtly smaller than distal one.
Before considering the ions in detail, we need to note that Manceau and Charlet (1994) concluded that selenate, sulfate, phosphate, selenite, and arsenate all formed bidentate
inner-sphere complexes with the surface.
We hypothesize that His could bind via coulombic interaction with the phosphate groups by forming a bidentate
ionic complex with the two positive groups (imidazole and alpha-amino, which both bear half-positive charge at pH = pI).
In the case of MDI foams, it seems that the covalent network is of good quality even at high water/low MDI indices; however, the virtual network, consisting of the hard segments, is very weak as reflected by the high swelling and nonexistent bidentate
carbonyl links (determined by FTIR).
For the purposes of this article, it is sufficient to note that anionic, cationic and neutral indium(III) complexes are known with a wide range of monodentate and bidentate
ligands, and that coordination numbers between 3 and 6 have been identified.
