<jats:title>Abstract</jats:title><jats:p>Herein we report the synthesis of a crystalline graphitic carbon nitride, or g‐C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>, obtained from the temperature‐induced condensation of dicyandiamide (NH<jats:sub>2</jats:sub>C(NH)NHCN) by using a salt melt of lithium chloride and potassium chloride as the solvent. The proposed crystal structure of this g‐C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub> species is based on sheets of hexagonally arranged s‐heptazine (C<jats:sub>6</jats:sub>N<jats:sub>7</jats:sub>) units that are held together by covalent bonds between C and N atoms which are stacked in a graphitic, staggered fashion, as corroborated by powder X‐ray diffractometry and high‐resolution transmission electron microscopy.</jats:p>
