Popis:	The hydrothermal reaction of (NH4)2B4O7, NaVO3, ethylenediamine, MnCl2·4H2O 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]·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{B8 O17(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) A , β = 98.820(1)°, Z = 4, D cadv = 2.282 g cm −3 ; R = 0.0462 for 7299 reflections.
