Structure Reports A – serie

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.

Starting with Volume 30, 1965, Structure Reports is produced in a new format by photo-offset printing from typed manuscript with unjustified lines. At the time when the decision for this change was taken, the cost of setting the manuscript in type was becoming so high as to render the cost of individual subscription pro­ hibitive. At that time automatic typing methods giving justified lines, etc. for photo-offset reproduction did not offer any saving over type setting, but hand typing of the manuscripts could give a considerable saving in production costs. In the belief that a publication that is too expensive to buy is of little value, the format has been changed sacrificing elegance to availability. The new format does not lead to increased length of the volumes since the information content of the typed and typeset pages is practically identical. How­ ever, the amount of work to be reported demands the eventual separation of Structure Reports into two volumes, A. Metals and Inorganic and B. Organic. It was convenient to introduce this change also at Volume 30, and with Volume 31 further to restrict the publication of crystal data, so that from 1966 onwards the reports deal almost entirely with complete structure determinations only. In the past the aim of Structure Reports has been to present critical reports on all work of crystallographic structural interest, whether it is derived directly from X-ray, electron or neutron diffraction, or even indirectly from other experiments.

The present volume continues the aim of Structure Reports to present critical accounts of all crystallographic structure determinations. The increase in the number of crystal structure papers (now about 2000 per year in the Organic Section) has prompted a minor change in format, which increases the information density per page, hopefully without any loss of clarity. Details of the arrangement in the volumes, symbols used etc. are given in previous volumes (e.g. 41B or 42A, pages vi-viii). University of British Columbia 1.
