A tetranickel(ii) macrocyclic complex incorporating five different bridging groups

Abstract

The synthesis and crystal structure of the tetranickel(II) complex [Ni ₄ (L ¹ )(OH)(MeCO ₂ ) ₃ (MeCO ₂ H)] is reported, where H ₄ L ¹ is a macrocyclic ligand incorporating thiophenolate, alkoxo and imine donors; the faces of the tetranickel array are differentiated and two of the nickel ions share three monatomic bridges (S,O,O).
