Reciprocal lattice sections hk[\textstyle\bar{1\over 2}], hk0 and hk[\textstyle{1\over 2}] around the 300 Bragg reflection of the hexagonal setting of the unit cell reconstructed from new CCD data images collected from a single crystal of Pb3(As0.52,P0.48O4)2 at ambient conditions by X-ray diffraction. Each Bragg peak is surrounded by four or six diffuse satellites that are indexed by half-integer values of h, k and l on the trigonal unit cell. The diagram on the right indicates the indexing with monoclinic indices of two sets of satellites on the unit cells of the three possible domain orientations. Note that the 300trig reflection only has four diffuse satellites because the pair that would correspond to domain T1 is forbidden by the C2/c symmetry of the monoclinic structure. Sample synthesized by Bismayer & Salje (1981BB9).
