Structural families

If the sampling interval is too short, the total number of structures that belong to iinic iie structural families is small compared to the total number available. If the sampling interval is too large, the total number of available structures is small, and you can m iss iinic ue conformations.

In another chapter concerning the intermetallic crystallochemistry (Chapter 7), a number of selected structural prototypes are described presenting some of their typical features and commenting on their distribution among different types of alloys. Attention is especially given to relationships between different prototype structures, and examples of their possible grouping in structural families are underlined. This chapter, therefore, could possibly be used as a first draft of a gazetteer of intermetallic structure types and could be considered as an introduction (partial and provisional indeed ) to the descriptive systematics of intermetallic crystal chemistry.

This structure type has been described as a member of the A1B2 structure family. 

This structure is a distortion of the Ni2In type which is described in 7.4.3.14 together with a AlB2-derivative structure family. 

AlB2-type variants and derivative structures. A number of A1B2-type related structures are here presented in order to emphasize the role that structural characteristics such as those present in the A1B2 type may play in a variety of intermetallic phases and to illustrate an example of a structure family containing numerous members interrelated by various kind of more or less large deformations or substitutions. Reference to a seminal paper by Gladyshevskii et al. (1992) will especially be made. 

It is worth to mention that this definition is not always consistent with the nature of the macromolecular assembly when applying to nucleic acids. For example, from all different types of quadruplex nucleic acids only quadruplex monomers are covered by lUPAC definition of tertiary structure being a single chain of DNA or RNA. However, also the quadruplexes with higher molecularity of the formed structures (dimers, tetramers) belong to this important tertiary structure family.
