Single crystals of mercuric bis(N‐imino‐methyl‐formamidate), Hg(Imf) 2 , were obtained from aqueous solutions of 1,2,4‐triazole and Hg(NO 3 ) 2 ·2H 2 O. The crystal structure [monoclinic, P 2 1 / c (no. 14), a = 499.6(2), b = 1051.2(4), c = 711.1(3) pm, β = 117.55(1)°, Z = 2, R 1 for 890 reflections with I 0 >2 σ (I 0 ): 0.0369] contains linear centrosymmetric Hg(Imf) 2 molecules with Hg–N distances of only 203.5(7) pm. Two plus two intra‐ and intermolecular nitrogen atoms add to an effective coordination number of 6.
