Structure and Magnetic Properties of an Original {CuIIMnIIWV} Heterotrimetallic Coordination Polymer

A monodimensional heterotrimetallic coordination polymer of formula(1)(infinity)[{(CuMnL2)-Mn-II-L-II}(3){(mu-NC)(3)W-V(CN)(5)}(2)]center dot H2O (1) has been assembled from pre-designed [(CuMnL2)-Mn-II-L-II](2+)cationic modules and homoleptic [W-V(CN)(8)](3-)metalloligands (H(2)L(2)is the compartmental Schiff-base resulting from the stepwise condensation of 2,6-diformyl-p-cresol with ethylenediamine and diethylenetriamine). The magnetic properties of1have been investigated revealing a three-dimensional ordered antiferromagnetic ground state below 4 K resulting from different antiferromagnetic interactions between all the spin carriers (S= 1/2 Cu-II,S= 5/2 Mn-II, andS= 1/2 W(V)centers).
