The present volume continues the aim of Structure Reports to present critical accounts of all crystallographic structure determinations of metals and of inorganic compounds. Details of the arrangement in the volumes, symbols used etc. are given in volume 53A, pages v and vi. University of Guelph, G. FERGUSON Guelph, Ontario, Canada 4January 1992 [VI] STRUCTURE REPORTS SECTION I METALS Edited by J. Trotter (University of British Columbia) [I] 2 ARRANGEMENT The metals reports in this volume are arranged under the classifications: binary alloys, ternary alloys (within each of these classifications, the entries are sorted alphabetically by formula), hydrides, borides, carbides, silicides, pnictides (N, P, As), chalcogenides (S, Se, Te) (within each of these classif- ications, the entries are sorted alphabetically by formula on the elements other than that of the classification). See 47A, VII for further details. To find particular substances the metals formula index may be used. 3 A1Au 4 J. Less-Common Metals, 61, 347-354. P2 3, 6.9227, Z = 4, R = 0.042.
