The hydrothermal reaction of (NH4)2B4O7, NaVO3, ethylenediamine, MnC12 · 4H2O and H2O in the molar ratio 2.74:4:4:1:175 at 170°C for 5 days yields orange crystals of (H3NCH2CH2NH3)4[(VO) 12O4{B8O17(OH)4} 2{Mn(H2O)2}2] · H2O (1·H2O) in 75% yield. The structure consists of a continuous contorted V12 ring, constructed from edge-sharing V(IV) square pyramids. Two {B8O17(OH)4}14- chains nestle in the cavities formed by the V12 ring. The octahedral Mn(II) sites bridge two neighboring [(VO)12O4{B8O17(OH) 4}2]12- clusters to produce a mixed metal boron oxide network with two-dimensional covalent connectivity. Crystal data: monoclinic C2/c, a= 13.4324(2), b=19.6998(1), c=24.0521(3) Å, β=98.820(1)°, Z=4, Dcalc =2.282 g cm-3; R=0.0462 for 7299 reflections.
