The spatial arrangement of ligands 1 oriented by the complexed template ion during polymerization explains the unexpectedly high Cu 2+ : Fe 3+ selectivity of the polymer formed from [Zn( 1 )] 2+ with a cross‐linking agent, divinylbenzene. The ionic radius of the Cu 2+ ion is similar to that of the Zn 2+ template. The distinct loss of Zn 2+ on polymerization strongly suggests that a sandwich arrangement results; that is, the [Zn( 1 ) 2 ] 2+ complex forms from [Zn( 1 )] 2+ .
