摘要
The title compound Gd3BSi2O10 crystallizes in orthorhombic system,space group Pbca, with dimensions of a= 9. 630(1), b= 6. 959(1), c= 22. 792(3) A,V= 1527. 4(4) A 3, Z=8, Mr= 698. 73, Dc= 6.08 g/cm3, F(000) =2440, p= 262.5 cm-1, R=0. 047,,Rw=0. 053, based on 3750 with I≥3. 0 1(I) observed independent reflections. The structure contains two kinds of isolated anions: (BSi (1)O6)5- and(Si(2)O4)4- independently forming isolated sheets arranged alternately along the c axis. The Polyhedra of three crystallographically independent rare earth atoms Gd (1),Gd (2), Gd(3) are connected through edges-shared each other to form a three dimensional network structure.
