A three-dimensional copper(II) coordination polymer featuring the 2,3-dioxyquinoxalinate(-2) ligand: Preparation, structural characterization and magnetic study

The initial use of 1,4-dihydro-2,3-quinoxalinedione (H2L′) in CuII chemistry has led to a 3D coordination polymer featuring the 2,3-dioxyquinoxalinate (L2−) ligand; the complex has the extremely rare (82.10)-a, lig (LiGe) architecture and is characterized by the propagation of weak antiferromagnetic exchange interactions through the “quinoxaline” part of L2−.
