The first layered nitride superconductor is reported! The intercalation of lithium into the layered compound β-ZrNCl (which is shown on the inside front cover of this issue) results in electron transfer from the lithium to the ZrN layers and the conversion of semiconducting β-ZrNCl to a black metallic compound with a superconducting transition temperature of around 12.5 K. Interesting parallels with layered copper oxide superconductors and alkali-metal doped fullerene superconductors should provide insight into the mechanism of high-Tc superconductivity.
