| Abstract | This study presents the coordination modes and crystal organization of a calcium-potassium coordination polymer, poly[hexaaquabis( $_{4}-4-carboxybenzenesulfonato-$ $^{4}$ O $^{1}:$ O $^{1`}:$ O $^{1``}:$ O $^{4})bis($ $_{3}-4-carboxybenzenesulfonato-$ $^{2}$ O $^{1}:$ O $^{1`})calcium(II)dipotassium(I)],$ [CaK $_{2}(C$ $_{7}H$ $_{5}O$ $_{5}S)$ $_{4}(H$ $_{2}O)$ $_{6}]$ $_{n},$ displaying a novel two-dimensional framework. The potassium ion is seven-coordinated by four sulfonate and one carboxyl O atom located on five different acid ligands, two of which are unique, and by two symmetry-independent water O atoms. A pair of close potassium ions share two inversion-related sulfonate O-atom sites to form a dimeric K $_{2}O$ $_{12}$ unit, which is extended into a one-dimensional array along the a-axis direction. The six-coordinate Ca $^{2+}$ ion occupies a special position ( ) at (0, , ) and is surrounded by four sulfonate O atoms from two inversion-related pairs of unique acid monoanions and by two O atoms from aqua ligands. The compound displays a layered structure, with K $_{2}O$ $_{12}$ and CaO $_{6}$ polyhedra in the layers and aromatic linkers between the layers. The three-dimensional scaffold is open, with nano-sized channels along the c axis. |

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.
