A novel cobalt borophosphate, (NH(4))(2)(C(4)H(12)N(2))[CO(2)B(4)P(6)O(24)(OH)(2)]center dot H(2)O with the mixed cations has been synthesized under mild hydrothermal conditions. Its crystal structure. was determined by the single-crystal X-ray diffraction (tetragonal, I4(1)/a (no. 88), a=14.207(3) angstrom, c=24.956(6) angstrom, V=5037.09(2) angstrom(3), Z=8). The crystal structure consists of a new type of three-dimensional borophosphatic anionic partial framework, which is built from the condensation of the fundamental building unit (FBU) [B(2)P(3)O(14)(OH)]. The CoO(6) octahedra are enchased in such borophosphate network to form a complex open framework with a three-dimensional intersecting channel system, the voids of which are occupied by ammonium, dipronated piperazine ions and water molecules, respectively. The magnetic measurement of the title compound has also been investigated.
