Synthesis and Structure Determination of a New Organically Templated Scandium Fluorophosphate Framework and Its Indium Analogue. — The structures of
the isostructural title compounds (II) are determined by single crystal XRD. The compounds crystallize in the monoclinic space group P21/n with Z = 4. The structure consists of a framework of corner-sharing PO4 tetrahedra and MO4F(OH2) (M: Sc, In),
MO4(OH2)2, and MO4F2 octahedra forming six-membered channels which are occupied
by H2O and protonated DABCO molecules. The local environments around P, F, and
Sc in (IIa) are studied by 31 P, 19F, and 45Sc MAS NMR, 45 Sc MQMAS NMR, and
45
Sc/19F REDOR NMR spectroscopy. — (PARK*, H.; BULL, I.; PENG, L.; YOUNG,
