Abstract

The novel hemilabile ferrocenylbisphosphane 1,1′-bis(bis{2-[(dimethylamino)methyl]phenyl}phosphanyl)ferrocene, [Fe{C5H4P(C6H4CH2NMe2-o)2}2] (1), was synthesized by reacting bis(dichlorophosphanyl)ferrocene, [Fe{C5H4(PCl2)}2] with LiC6H4CH2NMe2-o. Treatment of 1 with gray selenium and anhydrous ZnCl2 yielded, respectively, the bisselenide (ferrocene-1,1′-diyl)bis(bis{2-[(dimethylamino)methyl]phenyl}phosphine selenide), [Fe(C23H28N2PSe)2] (2), and the dizinc complex [μ-1,1′-bis(bis{2-[(dimethylamino)methyl]phenyl}phosphanyl)ferrocene-κ2 N,P2 N′,P′]bis[dichloridozinc(II)] dichloromethane monosolvate, [FeZn2Cl4(C23H28N2P)2]·CH2Cl2 (3), and both have been structurally characterized. Both compounds crystallized with the asymmetric unit containing half a molecule and with the Fe atom on an inversion centre. A Hirshfeld surface analysis indicated that the most significant contributions to the crystal packing of 2 are from H...H (76.7%), C...H/H...C (13.2%) and Se...H/H...Se (7.1%) contacts, while those for 3 are from H...H (62.3%), Cl...H/H...Cl (24.4%) and C...H/H...C (10.9%) contacts.
