Li B P N , the first lithium nitridoborophosphate, is synthesized by two different routes using a Li N flux enabling a complete structure determination by single-crystal X-ray diffraction data. Li B P N comprises three different complex anions: a cyclic [P N ] , an adamantane-like [P N ] , and the novel anion [P B N ] . [P B N ] is the first species with condensed B/N and P/N substructures. Rietveld refinement, Li, Li, B, and P 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 Li N 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.
