| Popis: | Crystals of the formula (An)3[Cu4Cl7] (I) and (An)3[Cu8Cl10(C⊀ CCH2OH)]· 2H2O (II) were obtained in the system AnCl-CuCl-H2O-HC⊀ CCH2OH [An is the anilinium cation (C6H5NH3+)] and studied by X-ray diffraction analysis (DARCH diffractometer, λMoKα, θ/2θ scan mode; 1121 and 2433 unique reflections with F≥4Σ(F), R = 0.064 and 0.044 for I and II, respectively). Ciystals I are orthorhombic, space group Pbnm, Z = 4. a = 21.65(1), b = 11.006(5). c = 11.068(6) A; ciystals II are triclinic, space group P-l, Z = 2, a = 14.94(1), b = 12.242(8). c = 11.341(7) A, α = 106.77(5), β = 92.05(6), γ = 113.38(5)°. In contrast to I, the anionic copper acetylenide π-complex contains the propargylium ion whose terminal C⊀ C group acts as a double bridging π, Σ-ligand sim ultaneously bonded to four copper(I) atoms. Structural genesis of [Cu4Cl7]3−n] (I) and [Cu8C110(C = CCH2OH)]3− n (II) anions is considered. |
