Abstract

The hydrothermal reaction of Cu(CH₃CO₂) ₂·H₂O, Na₂MoO₄ and terpyridine at 140 °C for 48 h yields [Cu(terpy)Mo₂O₇] (1), a bimetallic one-dimensional oxide. The structure consists of ruffled chains of edge- and corner-sharing {MoO₅} square pyramids, decorated with {CuN₃O₂} '4+1' axially distorted square pyramids. The Cu(II) polyhedra are disposed so as to produce an alternating pattern of Cu-Cu distances across the {Mo₂O₂} rhombi of the chain of 6.25 and 6.82 Å. This structural feature is reflected in the magnetic properties which are characteristic of a dimer rather than a linear chain, consistent with an alternating antiferromagnetic Heisenberg chain.
