  摘要：

  The dirhodium(I) complex cis-[Rh-2(mphonp)(2)(CO)(4)] (1) was prepared by reaction of 5-methyl-7-phenyl-1,8-naphthyridin-2-one (Hmphonp) with [{RhCl(CO)(2)}(2)] in methanol in the presence of base (NaOMe). The mphonp(-) ligands adopt a head-tail orientation relative to one another and bridge the Rh(I) atoms in the O2,N1 coordination mode. Treatment of RhCl3 . 3H(2)O with mphonp(-) in methanol affords the dirhodium(II) complex [Rh-2(mphonp)(4)] (2) in which cyclometalation leads to a novel chelating N8,C72 mode by two of the naphthyridine ligands. The Rh(II) atoms are bridged by the remaining mphonp(-) ligands with the O2,N1 coordination pattern being supplemented by N-8 as an axial donor atom. This mode requires a pronounced tilting of the bridging ligands towards the Rh-Rh axis leading to very long Rh-O2 distances (av. 2.30(2) Angstrom) and wide Rh-N1-C2 angles (av. 133(2)degrees). The Rh-Rh distances are 2.883(4) and 2.566(3) Angstrom in complexes 1 and 2, respectively (X-ray analyses).
