A. INTRODUCTION 1
In a previous paper (Nowacki, 1942) I presented the results of a statistical survey of the space-group determinations that had been published up to May 30, 1942. Since that time I have received many inquiries as to the possibility of publishing these statistics in full. I have, therefore, decided to work over the entire material once again and to complete it insofar as possible.
The data were obtained from literature accessible to us up to June 30, 1948. For the years 1913 to 1939 the material came from Strukturbericht; from then on from the original literature or the abstracting journals (C.A., C.Z., M.A., etc.). The data given in the abstracts (S.B., C.A., etc.) were assumed to be correct, and, for these data, the original papers were not consulted. Since my 1942 publication about 800 new space-group determinations were added. The percentages of the compounds, which fall into the various space groups, are about the same now as they were in 1942.
The main table shows the distribution of about 3800 different compounds among the space groups. The compounds are subdivided according to composition into seven categories:
I. Elements and alloys, including arsenides, borides, hydrides, carbides, nitrides, phosphides, and silicides
II. Sulfides, sulfosalts, selenides, and tellurides
III. Oxides and hydroxides
IV. Halides, including oxyhalides
V. Bromates, chlorates, iodates, carbonates, nitrates, sulfates, and tellurates, in which the bonding with the oxygen is essentially covalent. These are Niggli’s (1930) crystalline compounds of the first kind.
VI. Aluminates, antimonates, arsenates, borates, cerates . . .
