An alternating chain consisting of dinuclear Cu(II) ions bridged by end-on bis(μ-dicyanamido-κN1,N5) ligands and hydrogen-bonded pairs of bis(pyrimidin-2-yl)amines, with unusually long Cu⋯Cu distances of 7.20 and 9.99 à : Synthesis, structure and mag

A novel di-bridged dicyanamide dinuclear copper(II) compound with the formula [Cu(dipm)(μ-dca)(H2O)(ClO4)]2 · 2EtOH has been synthesised and structurally characterised by XRD, IR, EPR and magnetic measurements; (dipm = bis(pyrimidin-2-yl)amine).
