Seven potassium rare-earth molybdates KRE(MoO4)2 (RE = Tb, Dy, Ho, Er, Tm, Yb, Lu) were synthesized by flux-assisted growth in K2Mo3O10. The crystal structures were determined using single-crystal X-ray diffraction data. The synthesized molybdates crystallize within the orthorhombic Pbcn space group (60). The structural parameters were compared to literature data, and the trendlines were calculated using data from both the literature and this current study. The unit cell parameters of a and c increase linearly whereas b decreases with larger RE cations, based on crystal radii. The unit cell volumes increase linearly and the densities decrease linearly with larger RE cations.
