Abstract - Summary 
(short description):
Single crystals of Rb4Cu4OCl (I), Rb2Cu3O(SeO3)4Cl2 (II), and RbCu3(OH)(SeO3)Cl4(H2O)2 (III) have been prepared by chemical transport reactions method from uO SeO2 RbCl CuCl2 mixture. The unit cell parameters were determined by the least squares method. Compound I has a monoclinic symmetry [s.g. 2/, a = 14.907(10) Å, b = 15.094(10) Å, c = 9.079(6) Å, β = 104.090(13), V = 1981(2) Å3, Z = 8]. The crystal structure have been solved by the direct methods from X-ray diffraction data and refined by the least-squares techniques to R1 = 0.0448 (wR2 = 0.0984) for 1745 reflections with |Fo| ≥ 4σF. Compound II has a triclinic symmetry [s.g. P1 ̅, a = 7.856(7) Å, b = 8.162(8) Å, c = 8.940(8) Å, α = 110.356(14), β = 109.905(14), γ = 100.567(14), V = 474.7(8) Å3, Z = 1]. The crystal structure have been solved by the direct methods from X-ray diffraction data and refined by the least-squares techniques to R1 = 0.0448 (wR2 = 0.0984) for 1612 reflections with |Fo| ≥ 4σF. Compound I has a monoclinic symmetry [s.g. P21/, a = 10.972(9) Å, b = 8.879(7) Å, c = 15.430(13) Å, β = 110.347(14), V = 1409(2) Å3, Z = 2]. The crystal structure have been solved by the direct methods from X-ray diffraction data and refined by the least-squares techniques to R1 = 0.0328 (wR2 = 0.0440) for 1680 reflections with |Fo| ≥ 4σF.
