[NiL1]3[Cr(CN)6]2·18H2O [L1 = 3,10-bis(2-hydroxyethyl)-1,3,5,8,10,12-hexaazacyclotetradecane]: a two-dimensional bimetallic assembly exhibiting antiferromagnetic ordering and metamagnetic behavior

Abstract

Reaction of K₃[Cr(CN)₆] with a square-planar macrocyclic Ni(II) complex leads to a 2D honeycomb-like layered complex with novel hydrogen-bonding linkages in the honeycomb. Magnetic studies reveal that the complex displays a long range antiferromagnetic ordering with T_N  = 12.6 K at low field, and metamagnetic behavior originating from intralayer ferromagnetic and interlayer antiferromagnetic interactions.
