Li47B3P14N42—A Lithium Nitridoborophosphate with [P3N9]12−, [P4N10]10−, and the Unprecedented [B3P3N13]15− Ion |

Abstract: | Li47B3P14N42, the first lithium nitridoborophosphate, is synthesized by two different routes using a Li3N flux enabling a complete structure determination by single‐crystal X‐ray diffraction data. Li47B3P14N42 comprises three different complex anions: a cyclic P3N9]12−, an adamantane‐like P4N10]10−, and the novel anion P3B3N13]15−. P3B3N13]15− is the first species with condensed B/N and P/N substructures. Rietveld refinement, 6Li, 7Li, 11B, and 31P solid‐state NMR spectroscopy, FTIR spectroscopy, EDX measurements, and elemental analyses correspond well with the structure model from single‐crystal XRD. To confirm the mobility of Li+ ions, their possible migration pathways were evaluated and the temperature‐dependent conductivity was determined by impedance spectroscopy. With the Li3N flux route we gained access to a new class of lithium nitridoborophosphates, which could have a great potential for unprecedented anion topologies with interesting properties. |
