Low temperature crystal structure and magnetic behavior of bis(2-amino-4-methylpyridinium) tetrachloridocuprate
Abstract
(4-MAPH)2[CuCl4] (4MAP = 2-amino-4-methylpyridine) (1) has been synthesized and characterized by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic space group C2/c. The tetrachloridocuprate(II)(2-) ions pack in layers parallel to the ab-face of the crystal which are well separated by double layers of the 2-amino-4-methylpyridinium cations. The anions generate a square layer via short Cl…Cl interactions due to the C-centering. Variable temperature magnetic susceptibility measurements indicate the presence of weak antiferromagnetic interactions within the layers (J ~ -1 K).
