Neutron-diffraction experiments on ceramic powders of YBa/sub 2/Cu/sub 3/O/sub 6+//sub x/ (nonsuperconducting, with x = 0.0 and 0.15) have confirmed the existence of long-range, three-dimensional, antiferromagnetic order of the Cu spins. The structure determination was aided by the use of uniaxially oriented powders. The ordering wave vector within a CuO/sub 2/ plane is (1/21/2) and the planes are coupled antiferromagnetically along the c axis. The Neel tempreature is 400 +- 10 K for the x = 0.15 +- 0.05 sample and approx. >500 K for x = 0.0.
