<SUP>1</SUP>H- and <SUP>13</SUP>C-NMR spectra of free ligands and their alkali metal complexes with a new type of crown ethers containing a ferrocene unit have been recorded. The change of chemical shifts in <SUP>1</SUP>H- and <SUP>13</SUP>C-NMR spectra was attributed to an electronic field effect and a conformational change on the metal complexation, respectively. The crystal structure of the complex of 1,4,7,10,13-pentaoxa[13]ferrocenophane with sodium thiocyanate was determined by the X-ray method. The crystals are orthorhombic, space group Cccn, with <I>a</I>=20.579(4), <I>b</I>=25.622(8) <I>c</I>=7.606(1) Å, <I>U</I>=4010(2) Å<SUP>3</SUP>, <I>Z</I>=8, <I>D</I><SUB>c</SUB>=1.48 g cm<SUP>−3</SUP>. The distances between the iron atom of a ferrocene nucleus and the incorporated sodium cation and between the sodium cation and the nitrogen atom of a counter anion are 4.129 and 2.541 Å, respectively. The results suggest that the iron atom of the ferrocene does not take part directly in complex formation and that the sodium cation forms a contact ion pair with the nitrogen atom of a counter anion.
