SrTcMn crystallizes in the trigonal R3m space group. Sr(1) is bonded to three equivalent Tc(1) and four equivalent Mn(1) atoms to form distorted SrMn4Tc3 hexagonal pyramids that share corners with three equivalent Mn(1)Sr4Tc3 hexagonal pyramids, corners with six equivalent Sr(1)Mn4Tc3 hexagonal pyramids, edges with three equivalent Mn(1)Sr4Tc3 hexagonal pyramids, and edges with six equivalent Sr(1)Mn4Tc3 hexagonal pyramids. All Sr(1)-Tc(1) bond lengths are 2.70 Å. There are three shorter (2.74 Å) and one longer (3.20 Å) Sr(1)-Mn(1) bond length. Tc(1) is bonded in a distorted hexagonal planar geometry to three equivalent Sr(1) and three equivalent Mn(1) atoms. All Tc(1)-Mn(1) bond lengths are 2.70 Å. Mn(1) is bonded to four equivalent Sr(1) and three equivalent Tc(1) atoms to form MnSr4Tc3 hexagonal pyramids that share corners with three equivalent Sr(1)Mn4Tc3 hexagonal pyramids, corners with six equivalent Mn(1)Sr4Tc3 hexagonal pyramids, edges with three equivalent Sr(1)Mn4Tc3 hexagonal pyramids, and edges with six equivalent Mn(1)Sr4Tc3 hexagonal pyramids.
