K4MoC4(N2O)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one C(2), one N(1), two equivalent N(2), and two equivalent O(1) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to one N(2), two equivalent N(1), and one O(1) atom. Mo(1) is bonded in a distorted octahedral geometry to two equivalent C(1), two equivalent C(2), and two equivalent O(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Mo(1) and one N(1) atom. In the second C site, C(2) is bonded in a 1-coordinate geometry to one K(1), one Mo(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one C(1) atom. In the second N site, N(2) is bonded in a 3-coordinate geometry to one K(2), two equivalent K(1), and one C(2) atom. O(1) is bonded in a distorted rectangular see-saw-like geometry to one K(2), two equivalent K(1), and one Mo(1) atom.
