On ammonium-bis(dithiocarbamato)-copper(I)-monohydrate and Mono(dithiocarbamato)-copper(I)
The title compounds NH4[Cu(S2CNH2) 2]¡¤H2O (A) and CuS2CNH2 (B) were prepared from aqueous alcoholic solutions by reaction of ammoniumdithiocarbamate with copper sulfate in presence of excess cyanide as reductive. (A) crystallizes in the orthorhombic space group C2221 (No. 20) with a = 8.9518(6), b = 9.6414(6) and c = 10.6176(8) A, Z = 4. (B) crystallizes in the orthorhombic space group P212 121 (No. 19) with a = 5.9533(4), b = 6.6276(4) and c = 9.4834(5) A, Z = 4. In the crystal structure of (A) copper has a tetrahedral surrounding of four monodentate dithiocarbamate ligands. These structural units form 2D nets stacked along [001]. Staggered chains consisting of H2O and NH4+ penetrate the crystal structure along [001] yielding additional coherence via hydrogen bonds. The crystal structure of (B) comprises a three-dimensional tetrahedral framework of CuS 4 units exclusively linked by vertices. The arrangement is reminiscent of a filled beta-cristobalite structure with the dithiocarbamate ligands extending into the hollow spaces. Thermal decomposition precedes stepwise finally giving Cu2S in each case.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: copper-catalyst, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1111-67-7, in my other articles.
