β¦ Synopsis
Nine new A 2 Mo 4 Sb 2 O 18 (AΒΌ Ce, Pr, Eu, Tb, Ho, Er, Tm, Yb, Lu) compounds have been synthesized by solid-state reactions. They are isostructural with six reported analogues of yttrium and other lanthanides and the monoclinic unit cell parameters of all fifteen of them vary linearly with the size of A 3 + ion. Single crystal X-ray structures of eight A 2 Mo 4 Sb 2 O 18 (A ΒΌCe, Pr, Eu, Gd, Tb, Ho, Er, Tm) compounds have been determined. Neat A 2 Mo 4 Sb 2 O 18 (A ΒΌPr, Sm, Eu, Tb, Dy, Ho, Er, Tm) compounds exhibit characteristic rare earth metal photoluminescence.
