• 論文の詳細を見る

• The crystal structures of (BEDT–TTF)<SUB>2</SUB>[MHg(SCN)<SUB>4</SUB>] (M=K at 298 and 104 K and M=NH<SUB>4</SUB> at 298 K) were determined by X-ray analyses. A donor layer and an anion sheet stack alternately along the <I>b</I>-axis. The packing pattern of the donor is close to α-phase, while an anion sheet constructs a thick two-dimensional polymer plane parallel to (010). The linkage of (<U>Remark: Graphics omitted.</U>) (or NH<SUB>4</SUB>) (<U>Remark: Graphics omitted.</U>) in an anion sheet is very unique. The band structure calculation indicates both a closed and an open Fermi surfaces, resembling that of κ-(BEDT–TTF)<SUB>2</SUB>[Cu(NCS)<SUB>2</SUB>].
