The crystal structure of lead cyanamide, PbNCN, has been refined on the basis of a single crystal grown from solution. PbNCN crystallizes in space group Pnma (Z = 4) with a = 555.66(4) pm, b = 386.77(2) pm, and c = 1173.50(8) pm. The cyanamide anion exhibits CΒ±N bond lengths of 116 pm and 130 pm, an

Graphite is a by-product of the calcium cyanamide process. This fairly well-crystallized graphite is described, it has an interlayer spacing of 335,8pm. The probable formation mechanism of well-ordered graphite at temperatures of 1W4150"C is discussed. Very likely, less organized carbon of higher th
