Reaction of cadimium(II) chloride CdCl2.6H2O with two equivalents of N-hydroxymethylsaccharin (Sac-CH2OH) (1) in the presence of NEt3 afforded the presumably tetrahedral complex [Cd(K2-Sac-CH2O)2] (2). The Sac-CH2O- ligand behaves as a bidentate chelate. Reaction of (2) with one equivalent of the bidentate ligands (dipos); Ph2P(CH2)nPPh2, (n = 1 dppm; 2 dppe; 3 dppp; 4 dppb), Ph2P(S)(CH2)P(S)Ph2 (dppmS2) afforded tetrahedral complexes of the type [Cd(K1-Sac-CH2O)2(diphos)] (3-7). The reaction with two equivalents of the monodentate ligands (phos); Ph3P or Ph3PS gave [Cd(K1-Sac-CH2O)2(phos)2] (8,9). The N-hydroxymethylsaccharinate anion acts as a monodentate ligand to the cadmium center through the hydroxymethyl oxygen atom. The complexes were characterized by physico-chemical and spectroscopic methods.

Hg(ii) ortho-cyano-aminothiophenolate (ocap) complexes [Hg{SC6H3XN(CN)}]n (X = H, Me, Cl, Br, NO2) have been prepared from dehydrogenation and C–S bond cleavage of 2-aminobenzothiazoles.

Pd(ii) ortho-cyano-aminothiophenolate (ocap) complexes have been prepared and crystallographically characterised, binding either as an S,N-chelate or bridging via CN coordination in phosphine complexes.

Addition of 2-aminobenzothiazole (abt) and substituted derivatives to Hg(OAc)

In the current study, six new tetrahedral Hg(II) complexes of 3-hydrazonoindolin-2-one (HZI) with diphosphines (dppm, dppe, dppp, dppb) or diimines (bipy, phen) ligands have been prepared and characterized by molar conductivity, IR, 1H, 13C, and 31P NMR spectra. Antibacterial activity of these complexes has been tested against three bacterial species: Staphylococcusepidermidis and Staphylococcusaureus (gram positive) and Citrobacerfreundii (gram negative). All complexes are more active against Staphylococcusaureus than amikacin, while [Hg2(HZI)2(dppm)2]Cl4 (1), [Hg(HZI)(dppe)]Cl2 (2), and [Hg(HZI)(Phen)]Cl2 (6) complexes are more active against Staphylococcusepidermidis than amikacin. The complexes 2, [Hg(HZI)(dppp)]Cl2 (3), and 6 are active against Citrobacterfreundii.

This research includes synthesis and characterization of some of Cd(II) complexes with (3-hydrazonoindolin-2-one)(HZI) ligand and amino pyridine ligands. Treatment equialmolar of CdCl2.2.5H2O and (HZI) ligand with two moles of n-aminopyridine (n-amp) (n:2,3,4) ligands afford a tetrahedral complexes of the type [Cd(HZI)(n-amp)2]Cl2, where (HZI) ligand behaves as a bidentate chelating fashion through the N atom of azomethine group and O atom of carbonyl group. Whereas the (n-amp)(n: 2,3,4) was bonded monodentate mode through the N atom of heterocyclic ring. The prepared complexes have been characterized by molar conductivity, elemental analysis, infrared spectra and 1H-NMR and 13C-NMR spectra. Also the evaluation of biological activity of the prepared complexes against two types of gram positive bacteria (Staphylococcus Epidermidis and Staphylococcus aureus) and (Citrobacer Freundii) and gram negative, all prepared complexes showed activity against Staphylococcus aureus more than amikacin, while the [Cd(HZI)(3-amp)2]Cl2 complex showed high activity against Staphylococcus Epidermidis and Citrobacter freundii more than another prepared complexes

Addition of 2-aminobenzothiazole and substituted derivatives to mercuric acetate in warm ethanol leads to the high yield formation of [Hg{SC6H3XN(CN)}]n resulting from loss of hydrogen and sulfur-carbon bond cleavage. Addition of phosphines affords a series of complexes in which the new ortho-cyano-aminothiophenolate ligands adopt three different binding modes.
