Abstract: The family of radical-cation salts β''-(BEDT-TTF) <subscript>4</subscript> [(A)M <superscript>3+</superscript> (C <subscript>2</subscript> O <subscript>4</subscript> ) <subscript>3</subscript> ]·guest (M = Fe, Cr, Ga, Al, Co, Mn, Rh, Ru; A = K <superscript>+</superscript> , H <subscript>3</subscript> O <superscript>+</superscript> , NH <subscript>4</subscript> <superscript>+</superscript> ) has produced superconductors, metals, semiconductors, and metal-insulators through introduction of different guest molecules into the structure. We present three new additions to the family β''-(BEDT-TTF) <subscript>4</subscript> [(A)Cr(C <subscript>2</subscript> O <subscript>4</subscript> ) <subscript>3</subscript> ]·guest with the guest molecules toluene, phenol, or salicylaldehyde. These new guests are liquid or solid additives within the electrocrystallisation medium. All three salts show metallic behaviour from room temperature down to <10 K and do not show a superconducting transition.<br />Competing Interests: There are no conflicts to declare.<br /> (This journal is © The Royal Society of Chemistry.)
