Summary: A monobasic bidentate ligand (H2L) was prepared from the reaction of cyanoacetic acid hydrazide with 1-(4-((1H-imidazol-2-yl)sulfonyl)phenyl)ethanone (ISE) in ethanol.
It is widely used in analytical applications of metal complexes and acts as an efficient bidentate ligand with two donor Nitrogen atoms to form metal complexes.
At the same time, tetrafluoroborate ion can act as mono- or bidentate ligand or to be in transient state between covalent-bonded and ionic, got its name of "semi coordination" in literature [2, 3].
The complex, di(morpholine)titanium dichloride (2a) which was first obtained by serendipity during the synthesis of complex (3a) was successfully synthesized using a chosen synthon and having bidentate ligand will have better catalytic activity than monodentate ligands.
In most of the complexes studied the Cis- configuration Fig(2), as bidentate ligand bonding both through the thion / thiol sulphur atom and the hydrazinic nitrogen atom.
