Mel'nyk O. Synthesis and crystal structure of allyl -complexes of copper(I) sulfamate.

By means of the alternating-current electrochemical synthesis crystals of the first 10 allyl -complexes of copper(I) sulfamate with allyl derivatives and also 1 -complex of К2[Cu(NH2SO3)3] composition have been obtained. Earlier complexes of copper(I) sulfamate were unknown. In the structures of all the complexes, with the only exception of cationic [Cu(4 allylthiosemicarbazide)]NH2SO3, NH2SO3- participates in the internal Cu(I) coordination sphere exhibiting its ambidentate character. It has been displayed that in the case of Cu(I) coordination with the strong donor tertial N and thiocarbonyl S atoms C=C bond of allyl group participates in Cu(I) coordination which proves a double bond ability to compete with strong donor atoms for a place in Cu(I) coordination environment. It has been shown a special role of NH2 group of sulfamate anion which due to the two hydrogen atoms, sutable for a formation of (N)H…О(NH2SO3) bonds, weakens a donor ability of nitrogen atoms of NH2-groups.
