Crystal structure of Cu(I) ?-complexes from the system CuBr?HBr-diallylamine

3-(diallylamino)propanenitrile ((C3H5)2NC2H4CN, L) π-complexes with copper(I) ionic salts. Syntheses and crystal structures of compounds [Cu(H+L)ClO4]ClO4 · H2O, [Cu(H+L)BF4]BF4 · H2O, and [Cu(H+L)(H2O)]SiF6 · H2O

“…Data on Cu(I) π complexes with N allyl derivatives of aminonitriles, i.e., with compounds simultaneously containing amino, nitrile, and C=C functions, are presently lacking. However, diallylcyanamide ((С 3 Н 5 ) 2 NCN, Daca) is formally close to these compounds and its copper complexes are known, for example, [CuX · Daca], X = Cl, Br [8], [Cu(Daca)(NO 3 )] [9], [Cu 2 (Daca)(H 2 O) 3 (CH 3 OH)]SiF 6 [10], and [Cu 4 OCl 6 (Daca) 4 ] [11,12].…”
