Abstract Colourless needles of mercurous dimethylglyoximato nitrate, Hg 2 (Dmg) 2 (NO 3 ) 2 , grow from a diluted nitric acid solution of mercurous nitrate and dimethylglyoxime. The crystal structure (triclinic, P1¯, a = 728.50(13), b = 1066.8(2), c = 1167.9(2) pm, α = 93.78(2)°, β = 94.16(2)°, γ = 98.61(2)°, R all = 0, 0726) contains the cations [Hg 2 (Dmg) 2 ] 2+ and “non‐coordinating” (NO 3 ) — anions. In the cation, two neutral dimethylglyoxime molecules coordinate bidentately with Hg—N distances in the narrow range of 236 to 239 pm to the mercurous ion, Hg 2 2+ , which exhibits a Hg—Hg bond distance of 252.23(8) pm).
