Structure and Magnetic Properties of an Original {Cu^IIMn^IIW^V} Heterotrimetallic Coordination Polymer

Abstract

A monodimensional heterotrimetallic coordination polymer of formula ∞1[{CuIIMnIIL2}3{(µ‐NC)3WV(CN)5}2]·H2O (1) has been assembled from pre‐designed [CuIIMnIIL2]2+ cationic modules and homoleptic [WV(CN)8]3– metalloligands (H2L2 is the compartmental Schiff‐base resulting from the stepwise condensation of 2,6‐diformyl‐p‐cresol with ethylenediamine and diethylenetriamine). The magnetic properties of 1 have 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 CuII, S = 5/2 MnII, and S = 1/2 WV centers).
