Cadmium cyanide Cd

Cyanide occurs most commonly as hydrogen cyanide in water, although it can also occur as the cyanide ion, alkali and alkaline earth metal cyanides (potassium cyanide, sodium cyanide, calcium cyanide), relatively stable metallocyanide complexes (ferricyanide complex [Fe(CN)6]-3), moderately stable metallocyanide complexes (complex nickel and copper cyanide), or easily decomposable metallocyanide complexes (zinc cyanide [Zn(CN)2], cadmium cyanide [Cd(CN)2]). Hydrogen cyanide and cyanide ion combined are commonly termed free cyanide. The environmental fate of these cyanide compounds varies widely (Callahan et al. 1979). [Pg.168]

The stmcture of cadmium cyanide Cd(CN)2 is comparable to those of silica Si02 and ice H2O (= OH2) with respect to the AB2 composition, A taking a tetrahedral position linked infinitely by B to form a 3D framework (Table 1). In addition, polycyanopolycadmate [Cd,-(CN)v] resembles polyoxopolysilicates SivO,r in its catenation behavior to form multidimensional infinite stmctures. Hence, silicate and other mineral stmctures are mimicked by cadmium cyanide and polycyanopolycadmates in the latter, the tetrahedral Cd can be replaced by such tetrahedral centers as Cu(I) to extend infinite catenation stmctures with cyanide anions. [Pg.868]
