Abstract: In the new nickel(II) complex [14,25-dichloro-2,11-diphenyltetracyclo[20.4.0.0^4,9.0^12,17]hexacosa-2,10,12,14,16,22,24,26-octaene-19,20-dionato(2-)]nickel(II) dichloromethane sesquisolvate, [Ni(C₃₄H₂₆Cl₂N₄O₂)]·1.5CH₂Cl₂, the nickel(II) ion is four-coordinate and displays approximately square-planar coordination geometry. It binds to two deprotonated oxamide N atoms and two imine N atoms of the macrocyclic ligand. The C atom of one of the two dichloromethane solvent molecules lies on a twofold axis.
