The crystal structure described by Mn(Mo3Se4)2 crystallizes in the trigonal R-3 space group. Mo(1) is bonded to one Se(2) and four equivalent Se(1) atoms to form a mixture of distorted edge and corner-sharing MoSe5 square pyramids. Mn(1) is bonded in a distorted body-centered cubic geometry to two equivalent Se(2) and six equivalent Se(1) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Mn(1) atom. In the second Se site, Se(2) is bonded in a 4-coordinate geometry to three equivalent Mo(1) and one Mn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
