1. The joint Rietveld refinement of the synchrotron XRD and ND patterns revealed that BaMn 0.2 M 0.8 O 2.6 N 0.4 have orthorhombic (Pnma) symmetries with moderate intra-octahedral distortions and minute octahedral tilting distortions. The unusual structural distortions of BaMn 0.2 M 0.8 O 2.6 N 0.4 , as compared with other Ba-based perovskite oxynitrides, are similar to the contrast between SrMn 0.2 M 0.8 O 2.6 N 0.4 and other Sr-based perovskite oxynitrides, and are ascribed to the enhanced covalency contributed from Mn 2+ . Conforming to the general attribute of oxynitride phases;M = Nb;Ta ? Sr:Ta ? Ba:Nb ? Sr:Nb. The band gaps of AMn 0.2 M 0.8 O 2.6 N 0.4 were also dependent on the cation composition, and decreased in an order, Sr:Ta ? Ba:Ta ? Sr:Nb ? Ba:Nb, where the type of M played the more important role
