Abstract

Mn^II(TCNE)I(OH₂) was isolated from the reaction of tetracyanoethylene (TCNE) and MnI₂(THF)₃, and has a 2-D structure possessing an unusual, asymmetric bonded μ₄-[TCNE]˙⁻. Direct antiferromagnetic coupling between the S = 5/2 Mn^II and S = 1/2 [TCNE]˙⁻ leads to magnetic ordering as a canted antiferrimagnet at a T_c of 171 K.
