A new open-framework manganese borophosphate, KMnBP2O7(OH)2, has been prepared under ionothermal conditions in the ionic liquid 1-butyl-1-methylpyrrolidinium bromide. Single-crystal X-ray diffraction analysis showed that KMnBP2O7(OH)2 [monoclinic, P21/c, a = 6.659(1), b = 12.049(2), c = 9.790(2) A, β = 109.12(3)°, V = 742.2(3) A3, and Z = 4] has an unprecedented open-framework structure.
