## Abstract The dication C~2~H has been investigated by __ab initio__ molecular orbital theory. It is found to have a linear (__D__~β__h__~), structure with a triplet (^3^Ο^β^~__g__~) ground state. Deprotonation to C~2~H^+^ is exothermic by 9.8 kcal/mol, but this process is hindered by a large barr
