| Abstract | Liquid X-ray scattering and Raman spectroscopy measurements have been made at 280 °C on binary and ternary mixtures in the system PbX2–Pb(NO3)2–(K,Na)NO3, where X = F, Cl, or Br. The furnaces and experimental techniques are described. The nitrate coordination of Pb(II) is shown to be Pb(NO3)2–4 in halide-free melts of Pb(NO3)2–(K,Na)NO3. The nitrate ions are asymmetrically bound via two oxygen atoms at distances of 2.4 and 3.1 Å and the lead(II) atoms is positioned slightly out of the nitrate plane. In melts containing halide ions X– complexes of formal composition Pb2X3+ are formed, with Pb—X—Pb angles of 84 and 81° for Pb2Cl3+ and Pb2Br3+, respectively. In Pb2F3+ only the Pb—Pb distance can be experimentally determined. The Pb—F—Pb angle ranges between 96 and 139°. A remarkable characteristic of these complexes is the occurrence of very shot Pb—Pb distance of 3.4–3.8 Å, suggesting a significant metal–metal interaction. |

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.
