Abstract

The single-crystal X-ray structure and variable temperature magnetic properties of the novel dicopper(II) anticancer drug analogue [{Cu2(HL)(H2PO4)2}2][NO3]2·2H2O [H2L = bis(pyridine-2-aldehyde) thiocarbohydrazone] is determined; the complex shows a dimer of dimeric {Cu2(HL)}3+ units with dihydrogenphosphato and sulfur bridges between the inequivalent CuII centres, resulting in three antiferromagnetic exchange interactions: a dominant intradimer J of –109 to –116 cm–1, and two weaker interdimer interactions.
