Two organically templated niobium and zinconiobium fluorophosphates: Low temperature hydrothermal syntheses of NbOF[(P[O.sub.4]).sub.2][([C.sub.2][H.sub.10][N.sub.2]).sub.2] and [Zn.sub.3](NbOF)[(P[O.sub.4]).sub.4][([C.sub.2][H.sub.10][N.sub.2]).sub.2]

The preparation of two new niobium and zinconiobium fluorophosphates, NbOF[(P[O.sub.4]).sub.2][([C.sub.2][H.sub.10][N.sub.2]).sub.2] and [Zn.sub.3](NbOF)(P[O.sub.4]).sub.4][([C.sub.2][H.sub.10][N.sub.2]).sub.2] (2) was carried out under hydrothermal conditions using ethylenediamine as a template. The topolocal relationships between the 4-connected network of (2) and several reported (3,4)-connected networks were discussed.
