Abstract Homoleptic cyanide compounds exist of almost all main group elements. While the alkali metals and alkaline earth form salts, cyanides lighter elements occur mainly as covalent compounds. This review gives an overview status quo element cyanido complexes. Information about syntheses are included well applications, special substance properties, bond lengths, spectroscopic characteristics...

IVANOVA, E., T. STAYKOVA and I. VELCHEVA, 2008. Cytotoxicity and genotoxicity of heavy metal and cyanide-contaminated waters in some regions for production and processing of ore in Bulgaria. Bulg. J. Agric. Sci., 14: 262-268 This study generalizes the data of investigations on cytotoxic and genotoxic effect of heavy metaland cyanide-contaminated waters in 2001, 2003 and 2005. The water samples ...

Hydrogen-cycling [NiFe] hydrogenases harbor a dinuclear catalytic center composed of nickel and iron ions, which are coordinated by four cysteine residues. Three unusual diatomic ligands in the form of two cyanides (CN(-)) and one carbon monoxide (CO) are bound to the iron and apparently account for the complexity of the cofactor assembly process, which involves the function of at least six aux...

The photochemical reaction of Tp'Rh(L)(eta2-PhN=L) [Tp' = tris-(3,5-dimethyl pyrazolyl)borate, L = CNCH(2)CMe(3)] to form the coordinatively unsaturated reactive fragment, [Tp'Rh(L)], in the presence of alkylnitriles has been studied. The [Tp'Rh(L)] complex has been shown to selectively activate the primary C H terminus of acetonitrile, propionitrile, butyronitrile, and valeronitrile. The resul...

Different cyanogenic bacterial strains (Chromobacterium violaceum, Pseudomonas fluorescens, Bacillus megaterium) were cultivated under cyanide-forming conditions in the presence of metal-containing solids such as nickel powder or electronic scrap. All microorganisms were able to form water-soluble metal cyanides, however, with different efficiencies. C. violaceum was able to mobilize nickel as ...

Cyanides, a diverse family of compounds containing the highly reactive cyanide anion (CN), are produced from both anthropogenic and natural sources. The cyanide compounds most commonly found in the environment include sodium cyanide, potassium cyanide, and gaseous hydrogen cyanide, the latter being the main form present in air. The use of the term ‘cyanide’ in this section refers to the cyanide...

Effects of cassava (Munihot escuknta Crantz)-borne organic cyanide and inorganic cyanide in the form of sodium cyanide on bone and muscle development were investigated in eighteen dogs of Nigerian breed. After 16 weeks of stabilization in the laboratory from the time of purchase when the dogs were fed on the same diet, they were randomly assigned to three experimental groups of six dogs each. T...
