A novel class of interpenetrated 3-D network of a dimeric cupric-tetracarboxylate unit

The hydrothermal reaction of Cu(II), fumaric acid and 4,4′-bipyridine (bpy) in equimolar amounts at 160 °C resulted in a new type of two-fold interpenetrating 3-D coordination network composed of tetracarboxylate dicopper(II) units bridged by bipyridine spacers.

A Three-Dimensional Homometallic Molecular Ferrimagnet

The first metamagnetic one-dimensional molecular material with nickel(ii) and end-to-end azido bridges

A novel single azido bridged one-dimensional Ni(II) chain, which represents the first metamagnetic one-dimensional metal–azido system with only end-to-end azido bridges, has been synthesised and characterised by a low temperature magnetic study. Lloret Pastor, Francisco, Francisco.Lloret@uv.es
