Heterometal Nitrosyl Complexes with Remarkable Electronic Structure: Preparation and Crystal Structure of R2[Fe(WS4)2(NO)], R2[Fe(WS4)(NO)2], R2[Co(WS4)2(NO)], and R[Co(WS4)(NO)2] (R = PPh4)The diamagnetic (exception 1a) compounds (PPh4)2[Fe(WS4)2(NO)] (1a), PPh4)2[Fe(WS4)(NO)2] (2a), (PPh4)2[Co(WS4)2(NO)] (3a), and (PPh4)[Co(WS4)(NO)2] (4a) were characterized by UV/VIS and IR spectroscopy, magnetic measurements and by complete X-ray structure analyses. For crystal data see Inhaltsübersicht. In addition unpublished crystallographic data for (NEt4)[Co(MoO2S2)(NO)2] are given.
