Аннотация: The complex salt [CU4(SCN2H4)(7)(NO3)](NO3)(SO4)(.)3.3H(2)O was synthesized via reaction of aqueous solutions of thiourea with copper nitrate at 80degreesC and studied using X-ray diffraction analysis. The conditions and reasons for the partial oxidation of thiourea to sulfate ions were established. The crystals are monoclinic: a =Показать полностью12.6072(7) Angstrom, b = 15.4265(8) Angstrom, c = 22.108(1) Angstrom, beta = 120.133(6)degrees, space group P2(1)/c, Z = 4. The crystal structure consists of [Cu-4(SCN2H4)(7)(NO3)](3+) complex cations, SO42-, and NO3- anions, and molecules of the water of crystallization. Three types of coordination of the Cu atom were distinguished in the structure: trigonal (Cu-S 2.213-2.279 Angstrom), tetrahedral (Cu-S 2.315-2.459 Angstrom), and trigonal-pyramidal (3+1) (Cu-S 2.26-2.288, Cu-O 2.68 Angstrom). The NO3 ligand was found to be orientationally disordered.
