Abstract
This chapter discusses the characterization of nets with higher connectivity than four. The major source of data for the nets in this chapter is the RCSR database. The five connected net is based on square planar pyramidal nodes and is less common than the bnn net based on nodes with trigonal bipyramidal coordination. There are two basic geometries for six-connected nodes— octahedral and trigonal prismatic, one or both may be present in these nets. Octahedral nodes are encountered in the pcu-net. Seven-connected nets are found in one compound and it seems to contain the wfq net. Eight connected nets are extremely rare. Nets with three- and six-connected nodes are a common class of nets and also include the rutile net. Nets with four- and six-connected nodes are rare in the field of molecular based nets. Nets with four- and eight-connected nodes contain the fluorite/flu net. A table concluding the summary of higher connected nets is also provided.
