The synthesis, structure and powder magnetic susceptibility of two new copp
er complexes: [(2-amino-5-iodopyridinium)CUCl3 and (2-amino-5-iodopyridiniu
m) 2CuBr4. 2H(2)O] are reported. Both the crystal structures and the powder
magnetic susceptibility support the magnetic structure of the complexes as
