Abstract | Solvothermal reactions of hexakis(4-formylphenoxy)cyclotriphosphazene $(H_{6}L1)$ with $Cd(NO_{3})_{2}·4H_{2}O$ in H $_{2}O$ /DMF under different synthesis temperatures produced two new compounds, namely, $\{[Cd_{3}(C_{42}H_{24}O_{18}P_{3}N_{3})$ $(H_{2}O)_{7}]·xGuest\}_{n}$ (1), and $\{[Cd_{2}(C_{42}H_{24}O_{18}P_{3}N_{3})$ $(H_{2}O)_{2}]·xGuest\}_{n}$ (2). Compound 1 exhibits a novel 3D framework adopting 2,4,6-connected 3-nodal topology with the point (Schläfli) symbol $\{4^{4}·6^{2}\}\{4^{5}·6^{2}·8^{8}\}\{4\}$ constructed from the joint of neutral $Cd_{2}$ SBUs, mono-Cd ions and L1 ligands . Compound 2 reveals a 2D crystal structure exhibiting a 3,6-connected 2-nodal kgd topology with the point (Schläfli) symbol $\{4^{3}\}_{2}\{4^{6}·6^{6}·8^{3}\}$ constructed from the connection of Cd centers and L1 ligands . In these two compounds, the ligands L1 are fully deprotonated, whose six extended carboxyl arms connect six different/same metallic nodes to form high dimensional frameworks. The variable reaction temperature must be responsible for the higher coordination number and versatile coordination modes of carboxylates in 1 compared to the ones in 2, resulting in the formation of a distinct crystal structure. In the solid state, both complexes are photoluminescent (LMCT) at room temperature. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
