- Abstract
- The crystals of [Cu(CH2=CH-CH2-NH3)(SO4)] were obtained by an ac electrochemical synthesis from N,N'-diallylguanidinium sulfate (which undergoes hydrolysis) and an ethanol solution of Cu(NO3)2 · 3H2O. The title compound was structurally characterized with the use of a twin crystal (a DARCh diffractometer, MoK(α) radiation, space group P21/n, a = 13.288(4) Å, b = 4.976(3) Å, c = 9.932(2) Å, γ = 97.47(4)°, V = 651.1 (5) Å3; Z = 4, R = 0.037 from 761 reflections with F ≥ 2σF). The copper(I) atom has a trigonal-pyramidal environment made by three oxygen atoms from different sulfate groups and the C=C bond in the equatorial plane. The coordinated C=C bond length is equal to 1.38(1) Å. The structure is built from chains arranged along the [010] axis, in which the SO4/2- anion coordinates with three metal atoms through two oxygen atoms. Effective charges on atoms were calculated to elucidate the role of the N-H···O hydrogen bonds in the sulfate anions functioning as acidoligands.
