Title: A new organically-templated cobalt borophosphate with a novel borophosphatic anionic partial structure

A novel cobalt borophosphate, (NH{sub 4}){sub 2}(C{sub 4}H{sub 12}N{sub 2})[Co{sub 2}B{sub 4}P{sub 6}O{sub 24}(OH){sub 2}].H{sub 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{sub 1}/a (no. 88), a=14.207(3) A, c=24.956(6) A, V=5037.09(2) A{sup 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{sub 2}P{sub 3}O{sub 14}(OH)]. The CoO{sub 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. - Graphical abstract: A new organically-templated cobalt borophosphate, (NH{sub 4}){sub 2}(C{sub 4}H{sub 12}N{sub 2})[Co{sub 2}B{sub 4}P{sub 6}O{sub 24}(OH){sub 2}].H{sub 2}O with a novel borophosphate 3D anionic partial framework has been synthesized under mild hydrothermal conditions. Highlights: > The first cobalt borophosphate with the 3D anionic partial borophosphate network. > A porous framework with an intersecting three-dimensional channel system. > The borophosphate compound with the mixed cations.
