R. Kato et al., P-PI-D INTERACTION IN THE (R(1),R(2)-DCNQI)(2)CU SYSTEM, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 285, 1996, pp. 143-150
Pressure effects in the iodine-containing p pi-d system (DCNQI)(2)Cu a
re mainly described. Electrical and magnetic properties of (R(1),R(?)2
-DCNQI)(2)Cu are quite sensitive to the substituents R(1) and R(2). A
variety of substituent effects would be generally understood in terms
of the amount of charge transfer from Cu to DCNQI which is sensitive t
o the N-Cu-N coordination angle. In the iodine-containing DCNQI-Cu sys
tem, however, an inter-stack LUMO ... LUMO interaction would also play
an important role.
