The occurrence of interpenetration in metal–organic and inorganic networks has been
investigated by a systematic analysis of the CSD and ICSD structural databases. For this
purpose, a novel version of TOPOS (a program package for multipurpose crystallochemical
analysis) has been employed, where the procedure of recognition of interpenetrating nets is
based on the representation of a crystal structure as a finite reduced graph. In this paper we
report a comprehensive list (301 Refcodes) of interpenetrating metal–organic 3D structures …

Interpenetration in metal-organic and inorganic networks has been investigated by a
systematic analysis of the crystallographic structural databases. We have used a version of
TOPOS (a package for multipurpose crystallochemical analysis) adapted for searching for
interpenetration and based on the concept of Voronoi–Dirichlet polyhedra and on the
representation of a crystal structure as a reduced finite graph. In this paper, we report
comprehensive lists of interpenetrating inorganic 3D structures from the Inorganic Crystal …
