K3TcC4(N2O)2 crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to two equivalent N(1), two equivalent N(2), and two equivalent O(1) atoms to form KN4O2 octahedra that share corners with two equivalent Tc(1)C4O2 octahedra. The corner-sharing octahedral tilt angles are 46°. In the second K site, K(2) is bonded in a 4-coordinate geometry to one N(1), one N(2), and two equivalent O(1) atoms. Tc(1) is bonded to two equivalent C(1), two equivalent C(2), and two equivalent O(1) atoms to form TcC4O2 octahedra that share corners with two equivalent K(1)N4O2 octahedra. The corner-sharing octahedral tilt angles are 46°. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Tc(1) and one N(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Tc(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one C(1) atom. In the second N site, N(2) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one C(2) atom. O(1) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Tc(1) atom.
