The novel iron(II) fluoride cluster [Fe-4(II)((LSSL1)-S-1)(2)F-6(MeCN)(2)](BF4)(2) ((LSSL1)-S-1 = di-2-(bis(2-pyridylmethyl)amino) ethyl disulfide) has been synthesized by reaction of the ligand (LSSL1)-S-1 with [Fe(MeCN)(6)](BF4)(2). The crystal structure shows that a tetranuclear iron(II) compound is formed through the bridging of two dinuclear iron(II) units by four fluoride anions. The F-19 NMR spectrum distinguishes both the terminal and bridging fluoride ions in this compound. The new compound is a rare Fe-II fluoride cluster with four Fe-II and four F- ions arranged in a nearly perfect square plane, which obtained its fluoride ions from the tetrafluoridoborate anion.
