A Contribution on the Crystal Structure of CuYW2O8, CuHoW2O8, and CuYW2O8Single crystals of (I) CuY2O8, (II), CuHoW2O8, and (III) CuYbW2O8 were prepared and investigated by X-ray technique. (I) crystallizes with triclinic symmetry, space group C11—P1 (a = 5.939 Å, b = 6.042 Å, c = 5.025 Å; α = 112.30°, β = 111.77°; Z = 1). (II) and (III) belong to monoclinic symmetry, space group C2h4—P2/n (II) (a = 10.045 Å, b = 5.808 Å, c = 5.021 Å; β = 94.38°; z = 2 (III) a = 9.948 Å, b = 5.824 Å, c = 5.008 Å; β = 93.36°; Z = 2). The crystal structures will be discussed with respect to other to copper rare earth tungstates.
Notes:
(I) CuHoW2O8, (II) CuHoW2O8 und (III) CuYbW2O8 wurden einkristallin dargestellt und röntgenographisch untersucht. (I) kristallisiert triklin, Raumgruppe C11—P1 (a=5,939 AÅ, b= 6,042 AÅ, c= 5,025 AÅ; α=112,30°, β=92,84°, γ= 111, 77°; Z- 1). (II) und (III) Kristallisieren monoklin, Raumgruppe C2h4—P2/n (II) (a = 10,045 AÅ, b = 5,808 AÅ, c = 5,021 AÅ; β = 94,38°; Z = 2). Der Aufbau und die Einordnung in die bislang bekannten Kupferlanthanoid-Oxowolframate werden Diskutiert.
