The compound described by Np2Tc3Ge4 crystallizes in the monoclinic P2_1/c space group. Np(1) is bonded in a 10-coordinate geometry to two equivalent Tc(1), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 7-coordinate geometry to two equivalent Np(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Tc site, Tc(2) is bonded to two equivalent Ge(1) and four equivalent Ge(2) atoms to form distorted corner-sharing TcGe6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Np(1), one Tc(2), and three equivalent Tc(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to four equivalent Np(1), two equivalent Tc(1), two equivalent Tc(2), and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
