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

Abstract

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(-)1, a=9.848(20), b=12.470(32), c=12.603(28)A, alpha=63.47(16) degrees, beta=74.56(16) degrees, gamma=76.03(17) degrees). IM-6 exhibits a new framework topology. The inorganic framework is built up of MO(4) (M=Co, Ga) and PO(4) tetrahedra. It displays a two-dimensional interconnected channel system running along the [0(-)11] and [100] directions and delimited by ten- and twelve-membered ring openings, respectively.

“…3. The average Ga-O tetrahedral, Ga-OtrigonalÀbipyramidal and Ga-O octahedral bond distances of 1.811, 1.860 and 1.943 Å , respectively, agree well with those reported in other gallophosphate and gallium diphosphonates [23][24][25][26]. The Ga-F trigonalÀbipyramidal and Ga-F octahedral bond distances of 2.046(1), and 1.961(1) Å , respectively, agree well with those reported in other gallofluorophosphate and gallium diphosphonates [25,26].…”

Syntheses and Crystal Structures of Three Organically Templated Gallium Phosphates

“…As far as we know, GaPO can be obtained, where SDAs play a crucial role, which like a lot of other microporous materials. Accordingly, GaPO frameworks exhibit great structural diversity by adjusting synthetic conditions in the presence of different SDAs, and many chain (1D), layered (2D), and three‐dimensional (3D) structures are known . As reported in literatures, the first heterometallic manganese gallium phosphate (MnGaPO‐4) displays the 3D anionic framework with piperazine as SDA, while NGP‐1 exhibits a unique 2D layered structure by using diethylenetriamine as SDA .…”
