| Abstract | Systematic explorations of new phases in the AgI-TiIV/VV/MoVI-iodate systems led to four new quaternary silver iodates, namely, Ag2Ti(IO3)6, Ag2(VO2)(IO3)3, Ag2(V2O4)(IO3)4, and Ag2(MoO2)(IO3)4. They represent the first examples of silver iodates containing d0 transition metal cations. Ag2Ti(IO3)6 is isostructural with K2Ti(IO3)6 and its structure features a zero-dimensional (0D) [Ti(IO3)6]2− anionic unit composed of non-distorted TiO6 octahedron corner-sharing with six IO3− groups. Such anions are further bridged by Ag+ ions into a 3D network. In both Ag2(VO2)(IO3)3 and Ag2(V2O4)(IO3)4, each vanadium(V) is octahedrally coordinated by one terminal and two bridging oxo anions as well as three iodate anions in unidentate fashion. Neighboring VO6 octahedra form a 1D vanadium(V) oxide chain via corner-sharing oxo anions, such chains are further decorated by iodate anions in bridging or unidentate fashion. Ag2(VO2)(IO3)3 features a thick triple layer composed of two Ag(2)(VO2)(IO3)2 and one Ag(1)IO3 sheet whereas Ag2(V2O4)(IO3)4 features a 3D network composed of 1D [(V2O4)(IO3)3]− anionic chains along the c-axis that are interconnected by [Ag4(IO3)2]2+ clusters. Ag2(MoO2)(IO3)4 is isostructural with K2(MoO2)(IO3)4 and its structure features a 3D network built from 0D [(MoO2)(IO3)4]2− anions further interconnected by Ag+ ions. Optical and luminescent property measurements as well as band structure calculations based on density functional theory (DFT) methods have also been performed. |

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.
