1,4,7,10-Tetrathia[10]-, 1,4,8,11-tetrathia[11]-, 1,5,8,12-tetrathia[12]-, and 1,5,9,13-tetrathia[13](1,1′)ferrocenophanes reacted with (CH<SUB>3</SUB>CN)<SUB>4</SUB>Pd(BF<SUB>4</SUB>)<SUB>2</SUB> to give the corresponding 1/1 complexes in good yield. The <SUP>1</SUP>H NMR spectra of the Pd(II) complexes were not rigid at room temperature, except for the complex of 1,4,7,10-tetrathia[10](1,1′)ferrocenophane. The <SUP>1</SUP>H and <SUP>13</SUP>C NMR spectra at low temperature showed that the Pd(II) complex of 1,5,9,13-tetrathia[13]ferrocenophane was a single compound, while the other three complexes were a mixture of two isomers. In the electronic spectra of the above series, the low-energy band shifted to the long-wavelength region and increased its absorbance according to the decrease in the size of the thiamacrocycle.
