A trinuclear Cu₂Mn complex, [Mn(CuL)₂(DMF)₂](SCN)₂, where H₂L is 3,10,18,21-tetra­azatetra­cyclo­[20.4.0.0^4,9.0^12,17]hexa­cosa-2,10,12,14,16,22,24,26-octa­ene-19,20-dionate(2−) and DMF is dimethylformamide

A new trinuclear Cu₂Mn complex, bis­(dimethylformamide)bis­[μ-3,10,18,21-tetra­azatetra­cyclo[20.4.0.0^4,9.0^12,17]hexa­cosa-2,10,12,14,16,22,24,26-octa­ene-19,20-dionato(2−)]bis­(thio­cyanato)dicopper(II)manganese(II),[Cu₂Mn(C₂₂H₂₀N₄O₂)₂(NCS)₂(C₃H₇NO)₂], has been synthesized and structurally characterized. The Cu^II atom is five-coordinated by four N atoms from the tetraza macrocycle and one dimethyl­formamide N atom. The central Mn^II atom is coordinated by four O atoms of the oxamide group and two N atoms. The Mn^II atom lies on a centre of symmetry. The Cu^II atoms reside in the cavities of the macrocyclic ligands.

A new nickel(II) complex, [NiL]·CH₃OH, where H₂L is 2-phenyl-3,10,18,21-tetra­azatetra­cyclo­[20.4.0.0^4,9.0^12,17]hexa­cosa-2,10,12,14,16,22,24,26-octa­ene-19,20-dionate(2−)

In the title compound, [2-phenyl-3,10,18,21-tetra­azatetracyclo­[20.4.0.0^4,9.0^12,17]hexa­cosa-2,10,12,14,16,22,24,26-octaene-19,20-dionato(2−)]copper(II) methanol solvate, [Cu(C₃₄H₂₈N₄O₂)]·CH₃OH, the Ni^II atom is coordinated by four N atoms from the doubly deprotonated tetra­aza ligand, L²⁻, in a square-planar coordination geometry. O—H...O hydrogen bonds link the complex to the methanol solvent mol­ecule.
