Hydrothermal synthesis and structural characterisation of a vanadium (V) borophosphate cluster containing solid: [Co(en)3][enH2]{V3BP3O19}·4.5H2O

Hydrothermal reaction of VOPO4·2H2O and [Co(en)3]Cl3 in sealed borosilicate glass tube yielded a vanadium (V) borophosphate cluster based solid, [Co(en)3][enH2]{V3BP3O19}·4.5H2O (VBPO). Crystal data: monoclinic space group, P21/c, Z=4, a=12.0709(7), b=14.2261(8) and c=18.1104(9) Å, β=95.067(1)0°, V=3097.8(3) Å3. Single crystal X-ray diffraction studies revealed that discrete [V3BP3O19] clusters are linked to counter cations and water molecules through a complex hydrogen bonding network.
