Materials Data on KCN by Materials Project

KCN crystallizes in the monoclinic Cc space group. The structure is three-dimensional. K1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent N3- atoms. There are a spread of K–N bond distances ranging from 2.90–3.18 Å. C2+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. N3- is bonded in a distorted single-bond geometry to four equivalent K1+ and one C2+ atom.氰化钾（KCN）以单斜晶系Cc空间群结晶。该结构为三维结构。钾阳离子（K1+）以畸变的矩形跷跷跷板型配位几何与四个等价的氮阴离子成键，其键合几何为畸变的矩形跷跷板型，钾阳离子与四个等价的氮阴离子（N3-）配位成键，K-N键的键长分布范围为2.90~3.18埃（Å）。碳阳离子（C2+）以单键几何与一个氮阴离子（N3-）成键，C-N键的键长为1.18埃（Å）。氮阴离子（N3-）以畸变的单键几何与四个等价的钾阳离子（K1+）以及一个碳阳离子（C2+）成键。
