The title compound, [Ni(C(40)H(28)N(4)O)], was obtained from a Grignard reaction of the respective formyl-porphyrin to yield {5-[hy-droxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II), followed by crystallization from methyl-ene chloride/methanol. The mol-ecule exhibits a ruffled macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (Δ24) of 0.26 Å and an average Ni-N bond length of 1.931 (2) Å. In line with the asymmetrical substituent pattern, the degree of distortion is slightly larger at point of attachment of the meth-oxy(phen-yl)methyl residue than at the unsubstituted meso position. The meth-oxy group attached to the chiral C atom is disordered in a 0.534 (4):0.466 (4) ratio.

In the crystal structure of the title salt, [Ni(C(3)H(3)O(4))(C(16)H(36)N(4))]ClO(4)·CH(3)CN, the macrocycle folds around the Ni(II) atom, which is also chelated by the carboxyl-ate monoanion. The geometry is a distorted NiN(4)O(2) octa-hedron. The formula units are connected by N-H⋯O hydrogen bonds into centrosymmetric dimers.

In the title salt, [Ni(C(7)H(6)NO(2))(C(16)H(36)N(4))]ClO(4)·H(2)O, the Ni(II) cation is O,O'-chelated by the benzoate anion and N,N',N'',N'''-chelated by the macrocycle ligand, confering a distorted octa-hedral geometry on the metal atom. The complex cations, perchlorate anions and uncoordinated water mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. The perchlorate ion is disordered over two positions in a 0.

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.

In the title compound, [Ni(C(6)H(4)NO(2))(C(16)H(36)N(4))]ClO(4), the macrocyclic unit adopts a folded conformation, allowing the two carboxyl O atoms to occupy two neighbouring coordination sites and thus form an additional four-membered chelate ring. The less crowded side of the macrocycle (that with the two asymmetric C-H groups) is directed towards the nicotinate anion and the asymmetric C-CH(3) groups are directed away from it. The macrocyclic NH groups neighbouring the C-CH(3) groups are also directed away from the nicotinate anion, while those NH groups which are near to the geminal methyl groups are directed towards the nicotinate anion.
