Materials Data on K2C7N4O by Materials Project
Abstract
K2C5N4O(C)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of four methane molecules and one K2C5N4O sheet oriented in the (0, 1, 0) direction. In the K2C5N4O sheet, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six N3- and one O2- atom to form distorted edge-sharing KN6O pentagonal bipyramids. There are a spread of K–N bond distances ranging from 2.80–3.07 Å. The K–O bond length is 3.06 Å. In the second K1+ site, K1+ is bonded to five N3- and two equivalent O2- atoms to form distorted KN5O2 pentagonal bipyramids that share edges with four KN6O pentagonal bipyramids and faces with two equivalent KN5O2 pentagonal bipyramids. There are a spread of K–N bond distances ranging from 2.89–3.19 Å. There are one shorter (2.89 Å) and one longer (2.94 Å) K–O bond lengths. There are five inequivalent C+1.71+ sites. In the first C+1.71+ site, C+1.71+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the second C+1.71+ site, C+1.71+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the third C+1.71+more »
