Abstract
The structure of the title tetranuclear cluster, C59H42N3O8P3Ir4, was determined by X-ray analysis. It crystallizes in the monoclinic space groupC2/c. The unit cell parameters are:a =47.277(6),b=10.519(3),c=23.025(4) Å, β=105.77(1)°. The iridium atoms form a nearly regular tetrahedron. Between Ir4 and N336 atoms exists a relatively strong bond, thus one of the phosphine ligands is bridging one coordinatingvia P and N atoms.
