| Abstract | In the title compound, $[Ru(C_{14}H_{16}N_{4})(C_{16}H_{8}N_{4})](PF_{6})_{2}·1.422CH_{3}CN,$ discrete dimers of complex cations, $[Ru(L–N_{4}H_{2})tape]^{2+}$ are formed $\{L–N_{4}H_{2}$ = 2,11-diaza[3.3](2,6)pyridinophane; tape = 1,6,7,12-tetraazaperylene}, held together by π–π stacking interactions via the tape ligand moieties with a centroid–centroid distance of 3.49 (2) Å, assisted by hydrogen bonds between the non-coordinating tape ligand α,α′-diimine unit and the amine proton of a 2,11-diaza[3.3](2,6)-pyridinophane ligand of the opposite complex cation. The combination of these interactions leads to an unusual nearly face-to-face π–π stacking mode. Additional weak C—H⋯N, C—H⋯F, N—H⋯F and P—F⋯π-ring (tape, py) (with F⋯centroid distances of 2.925–3.984 Å) interactions are found, leading to a three-dimensional architecture. The $Ru^{II}$ atom is coordinated in a distorted octahedral geometry, particularly manifested by the $N_{amine}—Ru—N_{amine}$ angle of 153.79 (10)°. The counter-charge is provided by two hexafluoridophosphate anions and the asymmetric unit is completed by acetonitrile solvent molecules of crystallization. Disorder was observed for both the hexafluoridophosphate anions as well as the acetonitrile solvate molecules, with occupancies for the major moieties of 0.801 (6) for one of the $PF_{6}$ anions, and a shared occupancy of 0.9215 (17) for the second $PF_{6}$ anion and a partially occupied acetonitrile molecule. A second $CH_{3}CN$ molecule is fully occupied, but 1:1 disordered across a crystallographic inversion center. |

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.
