Lanthanide organometallic chemistry based on the porphyrinogen skeleton: acetylene and ethylene bridging praseodymium and neodymium eta(5):eta(1):eta(5):eta(1)-bonded to meso-octaethylporphyrinogen
E. Campazzi et al., Lanthanide organometallic chemistry based on the porphyrinogen skeleton: acetylene and ethylene bridging praseodymium and neodymium eta(5):eta(1):eta(5):eta(1)-bonded to meso-octaethylporphyrinogen, CHEM COMMUN, (17), 1999, pp. 1617-1618
The reaction of meso-octaethylporphyrinogen-lanthanide complexes, [{(eta(5)
:eta(1):eta(5):eta(1)-Et8N4)M}Na(thf)(2)] [M = Pr, Nd], with NaC10H8 in an
ethylene or acetylene atmosphere leads to the isolation of dimeric species,
where the metals are bridged by the [C2H4](2-) and [C-2](2-) anions.
