Abstract

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, respectively. The tetranuclear anions in 1 are built from [Fe(NCS)(6)](3-) groups 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.

(Bu4N)(4)[Ag2Fe2(SCN)(12)] . 2 CH3NO2 (1): a = 1184.10(10), b = 1370.80(10), c = 1776.5(2) pm, alpha = 99.090(10), beta = 192.100(10), gamma = 100.360(10)degrees, V = 2715.5(4) . 10(6) pm(3), space group P (1) over bar;

(Et4N)(2)[Ag2Fe(SCN)(6)] (2): a = 1607.0(2), b = 1006.92(9), c =1096.13(9) pm, V = 1773.7(3) . 10(6) pm(3), space group Pnnm.
