The crystal structure of the high T/sub c/ superconducting phase in a Pb-doped Bi-Sr-Ca-Cu-O system (nominal composition Pb/sub 0.3/Bi/sub 1.7/Sr/sub 2/Ca/sub 3/Cu/sub 4/O/sub Y/) with a zero-resistance temperature of 107 K was determined with transmission electron microscopy. The investigation shows that the crystal structure, which is different from the Pb-free one, is monocline with dimensions a = 0.532 nm, b = 0.383 nm, c = 3.71 nm, ..cap alpha.. = ..beta.. = 90/sup 0/ and ..gamma.. = 134.8/sup 0/. A distinct change of wave vector of incommensurate modulation was also observed.
