Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A family of magnetic metal–organic frameworks, (Ph₃PMe)₂[M₂(TCNQ)₃] {M=Fe²⁺, Co²⁺, Ni²⁺ and Zn²⁺} have been prepared and structurally characterized. The honeycomb‐like "layers" consist of M^II ions doubly bridged with dinitrilomethane moieties of two 7, 7, 8, 8‐tetracyanoquinodimethane (TCNQ) dianions which are further connected through phenyl rings to form a 3D dianionic framework [M₂TCNQ₃]²⁻ with Ph₃PMe⁺ cations filling cavities that run along the <italic>c</italic> axis. Studies of the magnetic coupling through the TCNQ dianion in these structures revealed that it can promote long‐range magnetic ordering despite the long coupling pathway.</p> </abstract>
