Assembly of Six-Membered Vanadium Borophosphate Cluster Anions: Synthesis
and Structures of (NH4)2(C2H10N2)6[Ba(H2O)5]2[V2P2BO12]6� 2O and
(NH4)8(C3H12N2)4[Ba(H2O)7][V2P2BO12]6�H2O. ? Single crystals of (IV) and (V)
are synthesized by self-assembly of vanadium borophosphate cluster anions via interdiffusion of solutions containing the separate components. As revealed by single crystal
XRD, compound (IV) crystallizes in the triclinic space group P1 with Z = 1. Its structure contains the infinite chain anion [{Ba(H2O)5}2(V2P2BO12 )16 4- ]. Compound (V)
crystallizes in the monoclinic space group C2/c with Z = 4 and contains discrete
[Ba(H2O)7(V2P2BO12)6]16- cluster anions. ? (YUN, H.; DO*, J.; Bull. Korean Chem.
