By means of an alternating current electrochemical synthesis 10 pi, sigma (and sigma-)complexes of copper(I) fluoroionic salts (CuBF4, CuOOCCF3 and CuSiF6) with allyl derivatives of heteroatomic compounds, and 1 aquacomplex of Cu(II) - [Cu(H2O)6]SiF6 have been obtained and their crystal structure by single crystal X-ray method has been studied. F atoms of the anions, with the exception of [Cu((C3H5)2NC2H4CN)BF4], are not involved into the internal Cu(I) coordination sphere, whereas O atoms of CF3COO anion together with C=C bond form a Cu(I) coordination environment. Among N, O, S heteroatoms of the complex heterocycles only N-atoms are coordinated with Cu(I) in the structures of the investigated compounds (atom O of a morpholine core in [Cu2(C4H8ON(C3H5)(H2O)]SiF6 H2O is the only exception). (C)H...E (E= F,O) hydrogen bonds and directed Cu(I) (C=C) bond are the main factors of crystal engineering of Cu(I) pi-complexes with fluoro- containing anions. They also influence essentially on lengthening of the coordinated C=C-bond (up to 1.40(1) A).5635
