| 摘 要： | A new borate K3Pr3(BO3)4 has been prepared using a high temperature flux method and structurally characterized by single-crystal X-ray diffraction analyses.It crystallizes in triclinic system,space group P1 with a=9.0814(10),b=10.8052(12),c=14.0885(16)A,α=69.800(1)°,β=89.922(1)o,γ=89.892(1)°,V=1297.4(3)A^3,Z=4,Mr=775.27,Dc=3.969 g/cm^3,F(000)=1400,μ(Mo Kα)=12.11 mm^-1,R(F2>2σ(F2))=0.028 and wR(F2)=0.054.Interestingly,the crystal of K3Pr3(BO3)4 was twinned by pseudo-merohedry that is mimic monoclinic space group P2/c.The structure of K3Pr3(BO3)4 exhibits a three-dimensional(3D)network based on isolated anionic(BO3)3-units that are further bridged by K+and Pr3+ions.Furthermore,X-ray diffraction(XRD),IRspectrum and photoluminescence(PL)properties were studied.
