Zinc(II) and cadmium(II) complexes of a tridentate oximate ligand cleave 4-nitrophenyl acetate with rate constants surpassing by two orders of magnitude those reported as the maximum possible level for highly basic free oximate anions as a result of removal of the "solvational imbalance" of the nucleophile by metal coordination.

Heavy metals are, unfortunately, present in the air, water, and food supply. Cases of severe acute lead, mercury, arsenic, and cadmium poisoning are rare; however, when they do occur an effective, non-toxic treatment is essential. In addition, chronic, low-level exposure to lead in the soil and in residues of lead-based paint, to mercury in the atmosphere, in dental amalgams and in seafood, and...

Metal propionate hydrazinates, M (CH3CH 2COO)2 (N 2H4 )2 where M = Mn, Co, Ni, Zn or Cd, and mixed metal propionate hydrazinates with cobalt, M i^Q ^^C H ^C I-^C O O ^^I-L t^ where M = Mg, Mn, Ni, Zn or Cd, have been prepared and characterized by analytical, magnetic, spectral, thermal and X-ray diffraction studies. The thermal decomposition of the former complexes yields the metal oxides while...

Three new coordination polymers based on CuI and 2,3-dimethylpyrazine (2,3-dmpyz) were prepared, structurally characterized and investigated for their thermal and luminescence properties. In the ligand rich 2:3 compound [(CuI)2(2,3-dmpyz)3] (CuI)2 dimers are found, which are connected by the N-donor ligands into chains, whereas in the structure of the 1:1 intermediate [(CuI)(2,3-dmpyz)] (CuI)4 ...

Two tetrakis(phthalocyaninato) dysprosium(III)-cadmium(II) single-molecule magnets (SMMs) with different extent of phthalocyanine peripheral substitution and therefore different coordination geometry for the Dy ions were revealed to exhibit different SMM behavior, providing an easy way to tuning and controlling the molecular structure and in turn the magnetic properties of tetrakis(tetrapyrrole...

Substituted thiourea ligands are of interest because they possess various donor sites for metal ions and their application in separation of metal ions and as antimicrobial agents. The coordination of the sulfur donor atom led to interest in them as precursor for semiconductor nanoparticles. In this study, cadmium(II) complex of diethylthiourea was synthesized and characterized by elemental anal...

BACKGROUND The coordination chemistry of cadmium(II) with diamine ligands is of particular interest. The most common structure around cadmium(II) center in their complexes is tetrahedral, that is due the octet rule obeyed. Nevertheless, five and six-coordinated complexes are also well known. Now a day, many cadmium(II) complexes with chelate ligands were synthesized for their structural or appl...

In current study, nanoparticles and single crystals of a Zn(II) coordination complex, [Zn(dmph)I2](1), {dmph=2,9-dimethyl-1,10-phenanthroline(neocuproine)}, have been synthesized by the reaction of zinc(II) acetate, KI and neocuproine as ligand in methanol using sonochemical and heat gradient methods, respectively. The nanostructure of 1 was characte...

Medical vocabulary is complex, expanding, and convoluted not least because of the large numbers of compound terms. Formalized medical terminologies such as SNOMEDCT and ICD-10 take one of two strategies when representing medical language: so-called pre-coordination where valid compound terms are included explicitly in the terminologies and so-called post-coordination where the terminology consi...

Cadmium (Cd) contamination is a global environmental challenge that threatens human food security. Lime combined with five different organic materials (rape seed cake, mushroom residue, straw, sawdust, and corn cobs) (LOM) at application ratios of 1:1 lime sawdust nitro-compound fertilizer (Ca(NO3)2·4H2O, KH2PO4, KNO3) (LSF) rates were applied to Cd-contaminated soil. The present study investig...
