A three-dimensional Cu–Na heteronuclear coordination polymer based on iminodi­acetic acid

In a novel Cu–Na heteronuclear three-dimensional coordination polymer, the carboxyl­ate groups of iminodi­acetate (ida) ligands act as bridges and connect [Cu(ida)] and [Cu(ida)₂] building blocks in a 2:1 ratio, forming two-dimensional arrays. These layers are inter­connected into a three-dimensional structure by sodium ions.
