Organizing a bis(iminoylnitroxide) diradical into antiferromagnetically coupled chains by co-crystallization with dichloromethane

Abstract

1,3-Bis(4′,4′,5′,5′-tetramethyl-4′,5′-dihydro-1′H-imidazol-2′-yl-1′-oxyl)-5-iodobenzene (IPhIN₂) forms a co-crystal with dichloromethane (CH₂Cl₂) and some water, with columnar π-stacking of radical N–O moieties organized into antiferromagnetically exchange-coupled 1-D chains.
