The new compound 7HgI 2 .Fe(C 5 H 5 ) 2 was prepared by the reaction of solid tetragonal mercuric iodide with ferrocene vapours at 423 K. The product is a dark green powder, stable in air, and decomposes at 463 K. The cubic unit‐cell parameters (298 K) are: a = 20.12(2) Å, V = 8157.3 Å 3 , Z = 8, M r = 3366.8, D x = 5.49 Mg m −3 ; extinctions indicate a face‐centered space group. X‐ray (Cu Kα radiation) powder diffraction data (50 lines) are reported. The compound has interesting electrical properties. The JCPDS Diffraction File No. for 7HgI 2 .Fe(C 5 H 5 ) 2 is 35‐2000.
