Abstract
The crystal structure of lead cyanamide, PbNCN, has been refined on the bas is of a single crystal grown from solution. PbNCN crystallizes in space gro up Pnma (Z = 4) with a = 555.66(4) pm, b = 386.77(2) pm, and c = 1173.50(8) pm. The cyanamide anion exhibits C-N bond lengths of 116 pm and 130 pm, an d the N-C-N angle is 176 degrees. Quantum-chemical DFT calculations indicat e that the cyanamide unit is comparatively easy to distort.
