Popis:	The set of complexes bis-(μ:η1,η1-3,4,5-triaryl-1,2-diphosphacyclopentadienyl)-bis-(tetracarbonyl manganese(I)) (aryl = C6H5 (2a), p-FC6H4 (2b), p-ClC6H4 (2c)) undergo an irreversible rearrangement to mononuclear 3,4,5-triaryl-1,2-diphosphacymantrenes (3a–c). According to quantum-chemical calculations binuclear complexes 2 can be considered to be products of kinetic control and mononuclear species 3 are thermodynamically favorable compounds. The antiferromagnetic intramolecular interaction observed for complexes 2 can be effectively tuned by using substituents in the para-position of the arene ring, whereas mononuclear 1,2-diphosphacymantrenes 3 are diamagnetic.
