Sr Pu Pu Tc
SrPu2Tc crystallizes in the trigonal R3m space group. Sr(1) is bonded to one Pu(2) and three equivalent Tc(1) atoms to form distorted SrPuTc3 trigonal pyramids that share  a cornercorner with one Tc(1)Sr3Pu2 trigonal bipyramid and corners with six equivalent Sr(1)PuTc3 trigonal pyramids. The Sr(1)-Pu(2) bond length is 2.22 Å. All Sr(1)-Tc(1) bond lengths are 2.99 Å. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a single-bond geometry to one Tc(1) atom. The Pu(1)-Tc(1) bond length is 2.22 Å. In the second Pu site, Pu(2) is bonded in a linear geometry to one Sr(1) and one Tc(1) atom. The Pu(2)-Tc(1) bond length is 2.22 Å. Tc(1) is bonded to three equivalent Sr(1), one Pu(1), and one Pu(2) atom to form distorted TcSr3Pu2 trigonal bipyramids that share corners with six equivalent Tc(1)Sr3Pu2 trigonal bipyramids and  a cornercorner with one Sr(1)PuTc3 trigonal pyramid.
