The reaction of cyclo-P4Mes4C(NCy) (1) with two equivalents of [AuCl(tht)] (tht=tetrahydrothiophene) resulted in the formation of unusual sixteen-membered Au–P macrocycle 2. This macrocycle contains diphospha(III)guanidinate as a coordinating ligand, which is formed by P−P bond cleavage of 1. Macrocycle 2 was characterized by multinuclear NMR spectroscopy, mass spectrometry and X-ray crystallography.

Abstract
The reaction of cyclo-P4Mes4C(NCy) (1) with two equivalents of [AuCl(tht)] (tht=tetrahydrothiophene) resulted in the formation of unusual sixteen-membered Au–P macrocycle 2. This macrocycle contains diphospha(III)guanidinate as a coordinating ligand, which is formed by P−P bond cleavage of 1. Macrocycle 2 was characterized by multinuclear NMR spectroscopy, mass spectrometry and X-ray crystallography.
