AbstractThe potassium pentaborate KB5O7(OH)2 reported herein crystallizes in the monoclinic space group P21/c (no. 14) with the lattice parameters a = 904.8(2), b = 753.2(2), c = 1214.9(5) pm, β = 117.16(2)°, and V = 0.73663(5) nm3 (Z = 4). It is a disordered structural variant of an already known compound with the same composition (a = 766.90(3), b = 904.45(3), c = 1223.04(4) pm, β = 119.132(2)°, and V = 0.74101(5) nm3 (Z = 4)) reported by Wu in 2011. The disorder of the potassium cation in the single crystal structure determination of KB5O7(OH)2 presented here leads to a remarkably elongated a axis and a corresponding reduction of the length of the b axis in comparison to the ordered compound. The disordered variant was obtained through a hydrothermal synthesis from KNO3, B2O3, and Ce(NO3)3·6H2O with a molar ratio of 1:1:0.07.
