9.4.1. Introduction

In inorganic compounds, the intrinsic interatomic distances vary over a wide range, depending on atomic size, oxidation state, coordination number, bonding type, conditions of state, etc. The experimental values depend also on the conditions of measurement and possibly the defect structure of the sample in question.

To a first approximation, interatomic distances can be calculated from the sum of ionic radii taken from various tables. Mean values from experimental values from a limited number of structures determined up to 1960 are listed in International Tables for X-ray Crystallography (IT III, 1962[link]). Today, databases allow all experimental results determined up to the present to be summarized and subjected to statistical analyses. For the Inorganic Crystal Structure Database (ICSD) (Bergerhoff & Brown, 1987[link]), this analysis has been performed starting with 24 496 structure determinations in the 1990 version for all combinations of ions and atoms. For 8329 combinations, at least one distance inside the range 0 to 500 pm could be calculated. The statistical procedure is described in the following Section, and the results are given in Tables 9.4.1.1[link][link][link][link][link][link][link][link][link][link][link] to 9.4.1.12[link] for many pairs for which more than two distances had been determined. For more detailed discussions, and other ion pairs, the CD-ROM version of the ICSD is recommended. With the command `check distances' in the CVIS program for the ICSD, the general distance distribution of a combination of elements can be compared with the distance distribution in a specific phase. Extreme values can be traced to their origin.
