Abstract The X-ray crystal structure of 1, 3-adamantane-dicarbonamide† has been determined. Colourless, cube shaped crystals of C 12 H 18 N 2 O 2 crystallize in the monoclinic space group C2/c (# 15) with cell dimensions a= 7· 934 (3), b= 15· 543 (3), c= 9· 404 (2) Å, β= 93.63°; V= 1157.4 (5) Å 3 and Z= 4.1074 unique reflections with I net> 2.00 σ (I) on refinement afforded values of R= 0.039 and R w= 0.040.
