Two new crystals of chlorovanadates,Ba_8Cs_5V_8O_(24)Cl_(13)(1) and MgCsV_2O_6Cl(2),were grown in the molten salt media. 1 crystallizes in tetragonal,space group P4/mmm(No. 123),with a = 14.801(2),c = 12.341(3) ?,V = 2703.5(8) ?~3,Z = 2,Mr = 3015.56,F(000) = 2640,μ = 11.044 mm-1,Dc = 3.704 g/cm3,the final R = 0.0380 and wR = 0.0937 for 1654 observed reflections with I > 2σ(I). 2 crystallizes in a monoclinic space group C2/c(No. 15) with a = 11.128(2),b = 10.540(2),c = 6.9892(14) ?,β = 118.38(3)°,V = 721.2(2) ?~3,Z = 4,M_r = 390.55,F(000) = 712,μ = 7.997 mm-1,D_c = 3.597 g/cm~3,the final R = 0.0537 and w R = 0.1363 for 740 observed reflections with I > 2σ(I). 1 exhibits a novel 8-membered-ring [V_8O_(24)] consisting of 8 corner-shared VO_4 tetrahetra,but in 2,an infinite ladder-like [VO_3]_∞ chain is formed by VO_5 square pyramids through sharing the edges.
