The five integrated-stack chargetransfer salts [M(CsMe5)2] [TCNQ] (M=Mn, Cr) and [M(C5Mes)2] [TCNE] (M=Fe, Mn, Cr) are bulk ferromagnets, whereas [Fe(C5Me5)2] [TCNQ] was reported to exist as two different phases, a metamagnet and a paramagnet. We now report that with careful control of the crystallization conditions, it is possible to isolate a new structural phase of [Fe(C5Me5)2] [TCNQ] which is a bulk 3-D ferromagnet with Tc = 3.1 K. Thus [Fe(C5Me5)2] [TCNQ] is the first example of a single compound giving rise to three distinctly different magnetic phenomena, a finding that will permit an assessment of the subtle structural features that control magnetic ordering in this class of materials.
