In (Bu4N)(4)[Ag2Fe2(SCN)(12)] . 2CH(3)NO(2) (1) and (Et4N)(2)[Ag2Fe(SCN)(6)
] (2) the ambidentate SCN- anions link Ag+ with Fe3+ and Fe2+ centers, resp
ectively. The tetranuclear anions in 1 are built from [Fe(NCS)(6)](3-) grou
ps connected by Ag+ ions. In 2 the same bridging pattern leads to polymeric
anionic chains containing [Fe(NCS)(6)](4-) groups linked by Ag+- ions.
