AbstractSingle-crystal structure determinations of the low-temperature quartz modification of AlAsOThe refinements were carried out in space groupsThe high pressure behaviour of AlAsOFrom the shortening of intertetrahedral O – O distances and the changes of the shape of the Dirichlet domains of the oxygen anions, it can be concluded that the oxygen packing changes with increasing pressure in the direction of an arrangement corresponding to a cubic body-centered lattice. As in the case of SiO

A new diffraction pattern of the high-temperature and high-pressure polymorph Mg3(PO4)2-III (PDF 43-500) is given and indexed on the basis of a single-crystal structure refinement. It allows diffractogram indexing of the isostructural high-temperature and high-pressure form of Co3(PO4)2 (PDF 43-499).

Although only sparingly soluble in acetonitrile, lithium(1) bromide and iodide crystallize as acetonitrile adducts, structurally characterized as LiX/MeCN 1 : 2 and 1 : 4 respectively by single-crystal structure determinations. The bromide is a �,�′-dibromo-bridged dimer , ( MeCN )2LiBr2Li( NCMe )2)] (monoclinic, P21/n, a 7.624(2), b 12.61 2(2), c 8.047(3) � , β 98.94(3)°p; Z 2 dimers; R 0.038 for No 1081 'observed' reflections); Li-Br, N 2.534(7), 2.492(8); 2.031(9), 2.047(8) � respectively, with Li…Li, 3.17(1); Br…Br, 3.8989(9) � respectively. The iodide is ionic, [Li( NCMe )4]+1- (orthorhombic, P21221, a 20.66(1), b 12.208(6), c 8.4296) �, Z 6; R 0.062 for No 866).
