Novel hypophosphite hybrid perovskites of [CH₃NH₂NH₂][Mn(H₂POO)₃] and [CH₃NH₂NH₂][Mn(H₂POO)_2.83(HCOO)_0.17] exhibiting antiferromagnetic order and red photoluminescence.

ABSTRACT: Hybrid perovskites based on hypophosphite ligands constitute an emerging family of compounds exhibiting unusual structures and offering a platform for construction of novel functional materials. We report the synthesis, crystal structure, and magnetic and optical properties of novel undoped and HCOO^--doped manganese hypophosphite frameworks templated by methylhydrazinium cations. The undoped compound crystallizes in a three-dimensional perovskite-like orthorhombic structure, space group Pnma, with ordered organic cations located in windows between the perovskite cages expanding along the a-direction. Both conventional anti-phase tilting, unconventional in-phase tilting and columnar shifts in the a-direction are present. Doping with HCOO^- ions has
