(2016) 'Antiferromagnetism in a Family of S = 1 Square Lattice Coordination Polymers NiX2(pyz)2 (X = Cl, Br, I, NCS; pyz = Pyrazine).', Inorganic chemistry., 55 (7). pp. 3515-3529.


NiX2(pyz)2 have been synthesized and characterized using several magnetic probes. Except for X = Cl, long-range AFM order was found below TN = 1.9 (X = Br and NCS) and 2.5 K (X = I). In addition, Jpyz ∼ 1 K regardless of X, and D = 8 K for NiCl2(pyz)2, whereas D ∼ 0 for X = Br, I, and NCS based on ESR and heat capacity.
