摘要:

Two novel polyphosphides, NaP5 and CeP5, were prepared in a BN crucible by the reaction of elemental components under a high pressure of 3 GPa at 800-950 degreesC. The X-ray structural analysis showed that NaP5 crystallizes in an orthorhombic space group Pnma with a = 10.993(2) (A) over circle, b = 6.524(1) (A) over circle, c = 6.903(1) (A) over circle, Z = 4 and CeP5 in the monoclinic group P2(1)/m with a = 4.9143(5) (A) over circle, b = 9.6226(8) (A) over circle, c = 5.5152(4) (A) over circle, beta = 104.303(6)degrees, Z = 2. The crystal structure of NaP5 consists of a three-dimensional framework (3)(infinity)[P-5](1-) bonds among four crystallographically inequivalent phosphorus sites, with large channels hosting the sodium cations, while CeP5 is a layered compound containing (2)(infinity)[P-5](3-) polyanionic layers that are separated by Ce3+ ions. NaP5 exhibits the diamagnetic behavior, while the temperature-dependent magnetic susceptibility of CeP5 essentially follows the Curie-Weiss law. (C) 2003 Elsevier B.V. All rights reserved.
