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 from CSD, that are analyzed on the basis of their topologies. Interesting trends and novel features have been observed and distinct classes of interpenetrating nets have been envisaged, depending on the relationships of the individual motifs.

Modern engineering widely uses high temperatures in an oxygen atmosphere, ie, in an oxidative environment This calls for highly oxygen-resistant materials Metals and metal alloys whose mechanical strength and plasticity are suitable for designing the most sophisticated shapes often do not meet the current demands on thermal stability, especially in the presence of silicates; borates; alkalis; sulfur-, vanadium-, and lead-containing compounds, etc Oxygen-free ceramics, eg, metal carbides and nitrides, are more heat resistant; however, even these materials become unstable at high temperatures in oxidative environments and fail after a time to eventually produce oxides Therefore, using oxide ceramics in high-temperature processes has a crucial advantage Modern methods for manufacturing materials from oxides eventually involve sintering powders either of these oxides or of their chemical precursors Sintering imposes severe constraints on the shape of resulting products, especially in fabricating thin-walled profiles We suggest a fundamentally novel method for creating thin-walled oxide ceramics, based on the controlled oxidation of metallic preforms with retention of the preform’s shape Metal oxidation is a chemical process addressed in innumerable publications However, primary emphasis heretofore has been placed on protecting metals from
