Abstract :
Summary form only given. We report the structural, electrical and magnetic properties of the charge transfer complexes of [M(dto)/sub 2/](M=transition metals) as electron acceptors and TTF derivatives. Three dimensional alternating stacks of donor dimer and anion molecule are observed in the 2:1 complexes of BEDT-TTF and BEDO-TTF with M (dto)/sub 2/(M=Ni, Pd). While BEDT-TTF complex with Pt(dto)/sub2/ is 2:1 with DDADDA stacking. They are insulators (10/sup -4/-10/sup -5/Scm/sup -1/) and singlet-triplet type magnetic behaviors were detected in BEDT-TTF-Pt(dto)/sub 2/ and BEDO-TTF-Ni(dto)/sub 2/ complexes. BEDT-TTF and Pd(dto)/sub 2/ gave a metallic (ca.1Scm/sup -1/ at RT) 4:1 complex, whose crystal structure is similar to the oxalate analogues. BEDO-TTF and Cu(dto)/sub 2/ form a metallic complex (20OScm/sup -1/ at RT).
