Novel Cu(iii) bis-1,2-diselenolene complex with a highly extended 3D framework through Na+ coordination

Abstract

The crystal structure of a new Cu(III) complex with the ligand pds²⁻ (pds, pyrazine-2,3-diselenolate) shows a unique packing pattern with segregated stacks of complex molecules interconnected through the pyrazine N coordination to Na counterions, which complete their coordination environment with four water molecules.
