| Abstract | A three-dimensional crystal structure analysis has been carried out on the complex KHL2 where HL is isonitrosoacetophenone. Photographs, taken at 98 ± 5 K, about the a axis only, were measured with a densitometer to give 2211 observations. The unit cell is triclinic (space group P) with a= 6·217(9), b= 13·147(6), c= 9·516(4)Å, α= 99·64(2), β= 83·54(2), γ= 78·77(2)°, and Z= 2. The structure was solved by direct methods and has been refined by full-matrix least-squares calculations to a conventional R of 0·104.The two ligands (L) are joined by a short hydrogen bond (2·47 Å) and have equivalent bond lengths and angles. Both ligands interact with a potassium ion by chelation through the keto-oxygen and oxime-nitrogen atoms to form five-membered rings. Seven co-ordination round the potassium ion is completed by oxygen atoms which are shared with other potassium ions. The oxygens involved are the oxime-oxygen of one ligand and the keto-oxygen of the other ligand. These potassium–oxygen contacts result in a polymeric column parallel to the needle axis (a) of the crystal. The K ⋯ O and K ⋯ N distances lie in the range 2·72 to 2·98 Å. |

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.
