The synthesis, x-ray crystal structures and magnetic susceptibilities for two tetrahalocuprate salts are reported. Bis(2-amino-5-nitropyridiriLium) tetrabromocuprate monohydrate [(5-NAP)(2)CuBr4.H2O], 1is trictinic, P-1. The tetrabromocuprate ions pack to form quasi-Heisenberg, S=(1)/(2). quantum antiferromagnetic ladders with two identical Br... Br contacts of 4.07 Angstrom forming the rungs and a single Br... Br contact of 3.93 Angstrom forming the rails. Bis(2-amino5-nitropyridinium.) tetrachlorocuprate [(5-NAP)(2)CuCl4], 2, is monoclinic, P2(1)/n. The tetrachlorocuprate ions are square planer and pack in layers to form a rectangular lattice with Cl...Cl contacts of 4.09 Angstrom and 4.31 Angstrom. Preliminary magnetic data on 1 yields exchange constants of J(rung) = 25.4 K and J(rail) = 13.3 K.
