N2 - Two new niobium and zinconiobium fluorophosphates, NbOF(PO 4)2(C2H10N2)2 (1) and Zn3(NbOF)(PO4)4-(C2H 10N2)2 (2), have been prepared under hydrothermal conditions using ethylenediamine as a template. The structures were determined by single crystal diffraction to be triclinic, space group P1 (No. 2), a = 8.1075 (6) Å, b = 9.8961 (7) Å, c = 10.1420(8) Å, α = 111.655(1)°, β = 111.51(1)°, γ = 93.206(1)°, V = 686.19(9) Å3, and Z = 2 for 1 and orthorhombic, space group Fddd (No. 70), a = 9.1928(2) Å, b = 14.2090(10) Å, c = 32.2971 (6) Å, V = 4218.66(12) Å3, and Z = 8 for 2, respectively. Compound 1 is an infinite linear chain consisting of corner-sharing [Nb 2P2] 4-MRs bridged at the Nb centers with organic amines situated between chains, and compound 2, containing the chains similar to that in 1, forms a zeotype framework with organic amines situated in the gismondine-type [4684] cavities. The topology of 2 was previously unknown with vertex symbol 4·4·4·4· 8·8 (vertex 1), 4·4·4·82·8· 8 (vertex 2), 4·4·8·8·82·8 2 (vertex 3), and 4·4·4·8 2·8·8 (vertex 4). The topological relationships between the 4-connected network of 2 and several reported (3,4)-connected networks were discussed.
