Abstract
The crystal structure of the macrocyclic complex [Ni(PCHA)](ClO4)2 (II) (PCHA = 4-methyl-1,3,5,8,11,14-hexaazatricyclooctadecane) is described. In the presence of succinate acid, [Ni(PCHA)](ClO4)2 (II) is obtained by recrystallization of orange crystals of [Ni(PCHA)](ClO4)2 (I), whose structure has previously been identified. The [Ni(PCHA)](ClO4)2 (II)crystal belongs to the monoclinic P2(1)/c space group with a = 15.8561(3) Å, b = 9.4409(2) Å, c = 13.9297(2) Å, α = 90°, β = 94.8840(10)°, γ = 90°, Mr = 526.02, Z = 4, V = 2077.65(7) Å. The structure is ionic with [Ni(L)]2+ and two perchlorate anions with a supermolecular interaction.
