Description 1081-1090
The reactions of ferrocenylbisphosphine, [Fe{C5H4P(C6H4CH2NMe2-o)2}2] (1) comprising dangling amine functionalities
with CuX yielded dinuclear complexes [{Cu2(μ-X)2}{Fe(C5H4P(C6H4CH2NMe2-o)2)2}] (2, X = Cl; 3, X = Br; 4 X = I). The
reaction of 4 with pyridine affords a binuclear complex, [{Cu2I2(py)2}{Fe(C5H4P(C6H4CH2NMe2-o)2)2}] (5) (py = pyridine) in
which each copper atom is tetracoordinated. Similarly, treatment of 4 with 2,2'-bipyridine in 1:1 molar ratio afforded the
binuclear complex, [{Cu2I2(2,2′-bipy)}{Fe-(C5H4P(C6H4CH2NMe2-o)2)2}] (6). The equimolar reaction of 3 and 4,4'-bipyridine
affords [{Cu2Br2(4,4′-bipy)}2{Fe(C5H4P- (C6H4CH2NMe2-o)2)2}2] (7) in good yield. The complexes 2 and 4 have been
structurally characterized; both crystallize in the monoclinic space group with C2/c. In the crystal packing of 2 and 4, the
invention-related intermolecular C-HX (X = Cl and I) and C-H(ring) interactions are primarily responsible for the crystal
packing. A Hirshfeld surface analysis indicates that the most significant contributions to the crystal packing of 2 are from HH
(81.7%), CH/HC (12.4%), ClH/HCl (4.3%) contacts, while those for 4 are from HH (80.9%), CH/HC (12.1%),
IH/HI (5.4%) contacts.
