  • Ba[sub]4[Mn[sub]3N[sub]6], a quasi-one-dimensional mixed-valent nitridomanganate (II, IV)
    Ovchinnikov, A. ...
    The mixed-valent nitridomanganate Ba4[Mn3N6] was prepared using a gas%solid high temperature route. The crystal structure was determined employing high resolution synchrotron powder diffraction data: ... space group Pbcn, a = 9.9930(1) Å, b = 6.17126(8) Å, c = 14.4692(2) Å, V = 892.31(2) Å3, Z = 4. The manganese atoms in the structure of Ba4[Mn3N6] are four-fold coordinated by nitrogen forming infinite corrugated chains of edge-sharing [MnN4] tetrahedra. The chains demonstrate a complete charge order of Mn species. Magnetization measurements and first principle calculations indicate quasi-one dimensional magnetic behavior. In addition, chemical bonding analysis revealed pronounced Mn%Mn interactions along the chains.
