 Single crystal of PbCuP2O7 has been prepared by the conventional solid state reaction method. Its crystal structure has been determined from X-ray four-circle diffractometer data: P21/n, a=5.381(1), b=8.205(2), c=12.570(3)?, β=90.49(3)°,Z=4, R=0.054 for 1311 structure factors and 101 variable parameters. The frame-work of PbCuP2O7 consists of corner-sharing CuO5 square pyramids and P2O7 groups forming large tunnels running along α-axis. Pb atoms are located in the pentagonal shaped windows, which are formed by the edges of two square pyramid and three PO4 tetrahedra.
