title: (Benzoato-κO,O')(5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane-κN,N',N'',N''')nickel(II) perchlorate benzoic acid solvate.
abstract: In the title compound, [Ni(C(7)H(5)O(2))(C(16)H(36)N(4))]ClO(4)·C(7)H(6)O(2), the Ni atom displays a distorted octa-hedral coordination geometry with four N atoms of the ligand rac-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane (L) in a folded configuration and two benzoate (bz) O atoms. The [Ni(rac-L)(bz)](+) complex cation, perchlorate anion and benzoic acid mol-ecules engage in hydrogen bonding, with N⋯O distances between 2.970 (3) and 3.123 (3) Å and an O⋯O distance of 2.691 (3) Å.
