N2 - A new oxygen-deficient perovskite, LaSrCuAlO5, has been prepared. The compound crystallizes in the orthorhombic crystal system with the space group Pbcm. The unit cell dimensions (Z = 4) are a = 7.9219(6), b = 11.020(1), and c = 5.4235(4) Å. The compound is a layered copper oxide with a structure related to that of the mineral brownmillerite. Important structural features include buckled copper oxygen planes and nonmagnetic, insulating aluminum-oxygen chains that alternate with the copper oxygen planes along the 7.9-Å axis. Resistivity measurements show that LaSrCuAlO5 is a semiconductor (ρ{variant}300 K = 0.065 Ω cm) and magnetic susceptibility measurements demonstrate that the compound is paramagnetic down to 4 K.
