文摘

Square-planar S = ¹/₂ Ag^II ions in polymeric Ag(nic)₂ are linked by bridging nic monoanions to yield 2D corrugated sheets. Long-range magnetic order occurs below T_N = 11.8(2) K due to interlayer couplings that are estimated to be about 30 times weaker than the intralayer exchange interaction.
