| Abstract | Metal organic frameworks (MOFs) are a class of porous solids formed by linking metal centres or metal clusters by suitable organic ligands capable of generating porosity in the microporous and mesoporous regimes. They have been investigated extensively for their gas storage applications in the last two decades. Interpenetration is nature’s way of avoiding excessive free-space within the large porous networks by growing identical but independent networks within a parent network to decrease the solvent accessible voids and increase stability. A major challenge in MOF synthesis involves minimizing or completely eliminating the extent. In this paper, we report a zinc isonicotinate (or pyridyl-4-carboxylate, 4-PyC) MOF, 1, prepared by tuning the synthesis conditions to minimize interpenetration. The three-fold interpenetration presented in this material is unusual and has been compared to the other zinc isonicotinates to identify the differences contributing to the improved porosity. In addition, the thermal decomposition of 1 in an oxygen-deficient medium has been shown to yield significantly porous carbon embedded with ZnO nanoparticles. Graphical Abstract Control of interpenetration in a highly interpenetrated Zinc isonicotinate system has been achieved via systematic investigation of the synthesis conditions. Also, the conversion of the metal organic framework into a porous carbon embedded with ZnO nanoparticles under an oxygen-deficient atmosphere has been demonstrated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
