Abstract We reported the investigating results of the phase transition and phase structure for LaSc3(BO3)4 crystal. LaSc3(BO3)4 crystal exist three phases: high temperature phase α-LaSc3(BO3)4 with space group C2/c, medium temperature phase β-LaSc3(BO3)4 with space group R32 and low temperature phase γ-LaSc3(BO3)4 with space group Cc. Title compound γ-LaSc3(BO3)4 crystallizes in the monoclinic with space group Cc, and the unit cell dimensions, a=7.740(3) Å, b=9.864(2) Å, c=12.066(5) Å, β=105.48(5)°C, V=887.8(6) Å3, Z=4, DC=3.81 g/cm3, λ(MoKα)=0.71067 Å, F(000)=944, final R=0.040, RW=0.054 for 1840 observed reflection with I≥3σ〉(I).
