Two new barium vanadium borophosphate compounds, (NH4)2(C2H10N2)6[Ba(H2O)5]2[V2P2BO12]6·8H2O, Ba- VBPO1 and (NH4)8(C3H12N2)4[Ba(H2O)7][V2P2BO12]6·17H2O, Ba-VBPO2 have been synthesized by interdiffusion methods in the presence of diprotonated ethylenediamine and 1,3-diaminopropane. Compound Ba-VBPO1 has an infinite chain anion {[Ba(H2O)5]2[V2P2BO12]6}14., whereas Ba-VBPO2 has a discrete cluster anion {[Ba(H2O)7][V2P2BO12]6}16.. Crystal Data: (NH4)2(C2H10N2)6[Ba(H2O)5]2[V2P2BO12]6·8H2O, triclinic, space group P1 (no. 2), a = 13.7252(7) A, b = 15.7548(8) A, c = 15.8609(8) A, α = 63.278(1)o, β = 75.707(1)o, γ = 65.881(1)o, Z = 1; (NH4)8(C3H12N2)4[Ba(H2O)7][V2P2BO12]6·17H2O, monoclinic, space group C2/c (no. 15), a = 31.347(2) A, b = 17.1221(9) A, c = 22.3058(1) A, β = 99.303(1)o, Z = 4.
