Self assembly of a FeIII(L) complex with octacyano metallates [MIV(CN)8]4− (L = pentadentate macrocyclic ligand, M = Mo, W): Crystal structure and magnetic properties

The self assembly of [FeIII(L)]Cl2ClO4 (L = pentadentate macrocyclic ligand) with octacyano metallates [MIV(CN)8]4− (M = Mo, W) leads to bimetallic cyano-bridged 2-D coordination polymers of formula [{Fe(L)}3{M(CN)8}2]Cl·xH2O with M = Mo (2), or W (3). The structure of the tungsten analogue has been established by single crystal X-ray diffraction. The magnetic properties for both Mo and W derivative are reported.
