“…The 1 H NMR spectrum showed a broad single resonance at 3.95 ppm for the ferrocenyl protons. At room temperature, the Me 2 N groups in compound 3 show a broad singlet at 2.29 ppm, suggesting a dynamic behaviour in solution, which is consistent with the similar behaviour observed in ZnCl 2 {PC 6 H 5 -[C 6 H 4 (CH 2 NMe 2 )-o] 2 } (Dobri et al, 2020).…”

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,P:κ2 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.

The reaction between CdCl2 and PPh2{C6H4 [CH2N(CH2CH2)2O]-2} (1) in a 1:1 molar ratio resulted in the cadmium(II) complex CdCl2[PPh2{C6H4[CH2N(CH2CH2)2O]-2}] (2). The complex 2 was characterized in solution by NMR spectroscopy (1H, 13C, and 31P). Single-crystal X-ray diffraction studies revealed no intramolecular N→P interaction in 1. The phosphane ligand behaves as a P,N chelating moiety in the cadmium complex 2, thus resulting in a species containing distorted tetrahedral environments around cadmium and phosphorus. Short intermolecular interactions CH‧‧‧π aryl and CH‧‧‧O in 1 and CH‧‧‧π aryl and CH‧‧‧Cl in 2 resulted in supramolecular networks.
