Manganese(II) octa­uranium(IV) hepta­deca­sulfide

Single crystals of manganese(II) octa­uranium(IV) hepta­deca­sulfide, MnU(8)S(17), were grown from the reaction of the elements in a RbCl flux. MnU(8)S(17) crystallizes in the space group C2/m in the CrU(8)S(17) structure type. The asymmetric unit is composed of the following atoms with site symmetries shown: U1 (1), U2 (m), U3 (m), Mn1 (2/m), S1 (1), S2 (1); S3 (m), S4 (m), S5 (m), S6 (m) and S7 (2/m). The three U(IV) atoms are each coordinated by eight S atoms in a bicapped trigonal–prismatic arrangement. The Mn(II) atom is coordinated by six S atoms in a distorted octa­hedral arrangement.
