摘要
The reaction of CuX2. nH(2)O with HX [X = Cl, Br] and 2-amino-3-methylpyridine in aqueous solution gave compounds of the formula (3-MAP)(2)(CuX4) [3-MAP = 2-amino-3-methylpyridinium]. The compounds have been characterized by single-crystal X-ray diffraction. The complexes crystallize as salts with the 3-MAP cations separating layers of tetrahalometallate anions. Both compounds have two independent molecules in their asymmetric units. Weak antiferromagnetic interactions are observed, which suggest a primarily low-dimensional magnetic exchange network.
