Addition of a coligand in reactions of phosphonates with salts of late 3d metals can lead to more soluble and tractable materials, such as the {Co13 } cage shown (Co: green; P: purple). The structure contains two central PhPO32- ligands, surrounded by a hexanuclear cobalt helix, capped by seven further cobalt sites.
Keywords: P ligands; cluster compounds; cobalt; phosphonate ligands.
