| Abstract: | This paper deals with the synthesis of six σ-cyclohexylethynyl complexes of CoII and FeII and their characterization by chemical analysis, infrared and 1H NMR spectra, and magnetic measurements. Four of them are six-coordinate complexes, unsubstituted or substituted, namely K4M(C≡C—C6H11)6] nNH3(M = Co, n = 2; M = Fe, n = 0), K2Co(C≡C6H11)4(NH3)2] and K4Fe(CN)4-(C≡C—C6H11)2]. Two are four-coordinate complexes of formula (Ph3P)2M-(C≡C6H11)2] (M = Co, Fe). All are low-spin complexes, the magnetic moment for the six-coordinate Co(II) complexes, measured at various temperatures, being intermediate between low- and high-spin values. |
