| Abstract | A hydrothermal reaction of a mixture of Y(NO$_{3}$)$_{3}$, 1,2-benzenedicarboxylic acid (1,2-BDC) and NaOH gives rise to a new yttrium phthalate coordination polymer, [Y$_{4}$H$_{2}$O$_{2}$C$_{8}$H$_{4}$O$_{4}$)$_{6}$]$_{∞}$,I. The Y ions inI are present in four different coordination environments with respect to the oxygen atoms (CN6 = octahedral, CN7 = pentagonal bipyramid, CN8 = dodecahedron and CN9 = capped square anti-prism). The oxygen atoms of the 1,2-BDC are fully deprotonated, and show variations in their connectivity with Y atoms. The Y atoms themselves are connected through their vertices forming infinite Y-O-Y one-dimensional chains. The Y-O-Ychains are cross-linked by the 1,2-BDC anions forming a corrugated layer structure. The layers are supported by favourableπ…π interactions between the benzene rings of the 1,2-BDC anions. The variations in the coordination environment of the Y atoms and the presence of Y-O-Y interactions along with the favourableπ…π interactions between the benzene rings from different layers are noteworthy structural features. Crystal data: triclinic, space group =P−1 (no. 2),a = 12.6669 (2),b = 13.8538 (2),c = 16.0289 Å,α = 75.20 (1),β = 69.012 (1),γ= 65.529 (1)°,V = 2371.28 (7) Å$^{3}$,D $_{calc}$ = 1.922 g cm$^{−1}$, μ($_{MoKα}$) = 4.943 mm$^{−1}$. A total of 9745 reflections collected and merged to give 6566 unique reflections (R $_{int}$ = 0.0292) of which 5252 withI>2σ(I) were considered to be observed. FinalR $_{2}$ = 0.0339,wR $_{2}$ = 0.0724 andS = 1.036 were obtained for 704 parameters. |

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.
