The complete array of single strand ('split-stair') polymers for the 1 : 1 system CuX/monodentate nitrogen base, L, all X= Cl, Br, I, has now been synthesized and structurally characterized by using the highly hindered pyridine bases, L= acridine and quinaldine . Similar polymers, [ LCuX ] 8, are also obtained with L = 2,6-dimethylpyridine for X = Cl, Br (but not I which is a dimer , [LCuI2CuL]), and for L = 2,4,6- trimethylpyridine, X = Br, I (but not Cl, which is ionic [CuL2]+[CuCl2]-). A general feature of all polymeric structures, although diverse in space group and not isomorphous in respect of polymer disposition, is the presence of a short crystallographic axis (about 4 Š) as the unit translational repeat distance.
