摘要：

Niobium phosphate, M(r) = 203.88, orthorhombic, Pnma, a = 11.304 (2), b = 5.316 (2), c = 6.640 (2) angstrom, V = 399.0 (3) angstrom 3, Z = 4, D(x) = 3.39 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 31.8 cm-1, F(000) = 384, T = 296 K, R = 0.030, wR = 0.043 for 462 unique reflections (R(int) = 0.017) with F(o)2 > 3-sigma(F(o)2). The framework is built up from NbO6 octahedra and PO4 tetrahedra. The NbO6 octahedra share opposite corners to form infinite zigzag chains along the b axis. These parallel octahedral chains are interconnected to each other via corner-sharing PO4 tetrahedra.
