“…In the Ca 12 [Mn 19 N 23 ] structure, each of nine symmetrically independent nitrogen atoms is octahedrally coordinated by three Ca and three Mn atoms, bridging the Ca and Mn layers as expected for nitrogen in nitridometalates, especially in those bearing alkaline‐earth metals . Whereas three out of four symmetrically independent Ca atoms have an octahedral coordination environment of nitrogen atoms, Ca4 is five‐fold coordinated, an environment also observed in the Ca nitridomanganates Ca 6 [MnN 3 ]N 2 and Ca 3 [MnN 3 ] .…”

Two new calcium nitridomanganates, Ca [Mn N ] (P3, a=11.81341(3) Å, c=5.58975(2) Å, Z=1) and Ca [Mn N ] (P3‾ , a=39.477(1) Å, c=5.5974(2) Å, Z=1), were obtained by a gas-solid reaction of Ca N and Mn with N at 1273 K and 1223 K, respectively. The crystal structure of Ca [Mn N ] was determined from high-resolution X-ray synchrotron powder diffraction data, whereas single-crystal X-ray diffraction was employed to establish the crystal structure of the Ca [Mn N ] phase, which classifies as a complex metallic alloy (CMA). Both crystal structures have 2D nitridomanganate layers containing similar building blocks but of different levels of structural complexity. Bonding analysis as well as magnetic susceptibility and electron spin resonance measurements revealed that only a fraction of the Mn atoms in both structures carries a localized magnetic moment, while for most Mn species the magnetism is quenched as a result of metal-metal bond formation.

Two new calcium nitridomanganates, Ca12[Mn19N23] (P3, a=11.81341(3) Å, c=5.58975(2) Å, Z=1) and Ca133[Mn216N260] ( , a=39.477(1) Å, c=5.5974(2) Å, Z=1), were obtained by a gas–solid reaction of Ca3N2 and Mn with N2 at 1273 K and 1223 K, respectively. The crystal structure of Ca12[Mn19N23] was determined from high‐resolution X‐ray synchrotron powder diffraction data, whereas single‐crystal X‐ray diffraction was employed to establish the crystal structure of the Ca133[Mn216N260] phase, which classifies as a complex metallic alloy (CMA). Both crystal structures have 2D nitridomanganate layers containing similar building blocks but of different levels of structural complexity.
