The complexes trans-[FeCl2(depe)2] and trans-[FeCl2(dmpe)2](depe = Et2PCH2CH2PEt2, dmpe = Me2PCH2CH2PMe2) dissolve in acetonitrile and methanol to give 1 : 1 electrolytes. In methanol solution trans-[FeCl2(depe)2] reacts rapidly with a variety of π-acceptor ligands to yield cations of the type trans-[FeCl(L)(depe)2]+[L = CO, NO+, RCN, ½N2, and P(OMe)3] which have been isolated as their tetraphenylborate

丙酮溶液中,中性配合物的反应要慢得多,并且
配体L的范围更小。如果发生反应(L = CO或RNC),则会得到顺式和反式异构体的混合物,并且已将其分离出来。配合物反式-[FeI 2(
