Synthesis and Crystal Structure of IM-6, a New Open Framework Cobalt-Gallium Phosphate with Ten- and Twelve-Membered Pore Openings

A new three‐dimensional microporous cobalt–gallium phosphate, named IM‐6, has been synthesized under solvothermal conditions with an N‐substituted piperazine as organic template. The structure was solved by single‐crystal X‐ray diffraction (triclinic, P$\bar 1$, a=9.848(20), b=12.470(32), c=12.603(28) Å, α=63.47(16)°, β=74.56(16)°, γ=76.03(17)°). IM‐6 exhibits a new framework topology. The inorganic framework is built up of MO4 (M=Co, Ga) and PO4 tetrahedra. It displays a two‐dimensional interconnected channel system running along the [0 $\bar 1$ 1] and [1 0 0] directions and delimited by ten‐ and twelve‐membered ring openings, respectively.
