Abstract

K2Tc crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a 5-coordinate geometry to five Tc atoms. There are four shorter (3.84 Å) and one longer (3.95 Å) K–Tc bond lengths. In the second K site, K is bonded in a 5-coordinate geometry to five Tc atoms. There are a spread of K–Tc bond distances ranging from 3.79–4.05 Å. In the third K site, K is bonded to four Tc atoms to form a mixture of distorted edge and corner-sharing KTc4 tetrahedra. There are two shorter (3.51 Å) and two longer (3.64 Å) K–Tc bond lengths. In the fourth K site, K is bonded to four Tc atoms to form a mixture of distorted edge and corner-sharing KTc4 tetrahedra. There are a spread of K–Tc bond distances ranging from 3.49–3.70 Å. There are two inequivalent Tc sites. In the first Tc site, Tc is bonded in a 9-coordinate geometry to nine K atoms. In the second Tc site, Tc is bonded in a 9-coordinate geometry to nine K atoms.
