2-hydroxy-1-naphthaldehyde and ethylenediamine (naphth-enH2), o-phenylenediamine (naphth-phH2), and 4-methyl-o-phenylenediamine (naphth-mphH2) form with cobalt(II) acetate and iron(II) perchlorate in methanol under nitric oxide the tetragonal pyramidal mononitrosyls [M(NO)(naphth-en)], [M(NO)(naphth-ph)] and [M(NO)(naphthmph)], where M=Co or Fe. The iron complexes have temperature-independent magnetic moments corresponding
通过将2-羟基-1-萘甲醛和乙二胺(naphth-enH2),邻苯二胺(naphth-phH2)和4-甲基-邻苯二胺(naphth-mphH2)缩合制备的四齿席夫碱一氧化氮中甲醇中的乙酸盐和高氯酸亚铁盐(II)的四角锥型单亚硝酰基[M(NO)(naphth-en)],[M(NO)(naphth-ph)]和[M(NO)(naphthmph)] ,其中M = Co或Fe。铁络合物具有与温度无关的磁矩,对应于三个未配对电子的存在(S = 32)。钴配合物是反磁性的,溶液中15NO标记的配合物的低场15N NMR位移(相对于MeNO2约为740 ppm)表明它们含有弯曲的CoN= O基团。
