| Abstract | Hydrothermal reactions of 1, 2, 4, 5-benzenetetracarboxylic acid (H$_{4}$BTC) with cadmium acetate and copper acetate in the presence of imidazole (imz) resulted in two new coordination polymers, namely, [Cd(imz)$_{3}$]$_{2}$(BTC)·0.5H$_{2}$O 1, [Cu$_{4}$(H$_{2}$O)$_{2}$(imz)$_{8}$](BTC)$_{2}$·7H$_{2}$O 2. Two compounds have been characterized structurally using single-crystal diffraction, elemental analysis, and FT-IR spectrum. In compound 1, the hexa-coordinated Cd(II) ions are bridged by BTC to form two-dimensional rhombohedral grid sheets. In compound 2, the coordination polyhedrons [CuO$_{4}$N$_{2}$] and [CuO$_{3}$N$_{2}$] are bridged by BTC to lead to a 2D framework with rectangular-shaped cavities. Two compounds of third-order nonlinear optical (NLO) properties were determined by Z-scan technique in DMSO solution. The results showed that two compounds exhibited strong NLO absorption and strong self-focusing effects. The third-order NLO absorptive coefficients β(MKS) are 5.45 × 10$^{−11}$ m W$^{−1}$ for 1 and 9.81 × 10$^{−11}$ m W$^{−1}$ for 2. The refractive indexes γ(MKS) are 3.96 × 10$^{−18}$ m$^{2}$ W$^{−1}$ for 1 and 7.60 × 10$^{−18}$ m$^{2}$ W$^{−1}$ for 2. The third-order NLO susceptibility χ$^{(3)}$ are calculated to be 1.25 × 10$^{−11}$ for 1, 2.32 × 10$^{−11}$ esu for 2, respectively. These values are larger than those of metal coordination polymers reported.Two novel two-dimensional transition metal coordination polymers have been reported. Two compounds exhibit strong NLO absorption and strong self-focusing effects. The third-order NLO susceptibility χ$^{(3)}$ are calculated to be 1.25 × 10$^{−11}$ for 1, 2.32 × 10$^{−11}$ esu for 2, respectively |

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.
