Crystal structures inorganic

The two major databases containing information obtained from X-ray structure analysis of small molecules are the Cambridge Structural Database (CSD) [25] and the Inorganic Crystal Structure Database (ICSD) [26] both are available as in-house versions. CSD provides access to organic and organometallic structures (mainly X-ray structures, with some structures from neutron diffraction), data which are mostly unpublished. The ICSD contains inorganic structures. 

ICSD is a numeric database with 65 000 inorganic crystal structures (December,... 

The Cambridge Structural Database (C5D) and the Inorganic Crystal Structure Database (ICSD) contain information obtained from X-ray structure analysis.

A few considerations about possible schemes of relationships between inorganic crystal structures based on a systematic construction of complex structural types by means of a few operations (symmetry operations, topological transformations) applied to some building units (point systems, clusters, rods, sheets), have been previously reported in 3.9.1, following criteria suggested, for instance, by Hyde and Andersson (1989) and by Zvyagin (1993).

The structures of many inorganic crystal structures can be discussed in terms of the simple packing of spheres, so we will consider this first, before moving on to the more formal classification of crystals. 

As the valency of the metal increases, the bonding in these simple binary compounds becomes more covalent and the highly symmetrical structures characteristic of the simple ionic compounds occur far less frequently, with molecular and layer structures being common. Many thousands of inorganic crystal structures exist, ffere we describe just a few of those that are commonly encountered and those that occur in later chapters. 

Each compound mentioned in this book is followed by its collection code (number) in the Inorganic Crystal Structure Database (Bergerhoff et al. 1983) or its refcode (letters) in the Cambridge Crystallographic Database (Allen et al. 1979). A reference to the original paper describing the structure of the compound is listed under this code in the literature references in Appendix 5. 

The lattice approach has also been used for the systematic description of inorganic crystal structures (Wells 1975, pp. 119-55 Hyde and Andersson 1989, pp. 6-49), but the method is not just geometric and descriptive. It has a sound physical basis and can therefore be used for structure modelling.
