Abstract
We analyze the specific features of the structure and properties of crystals that belong to the family of low-dimensional molecular conductors based on BEDT-TTF (ET) radical cation salts with [MNOX5]2s- (M=Os, Ru; X=Cl, Br) mononitrosyl metal complexes as anions. It is shown that when the synthesis components are changed single crystals with α’, β, δ, and κ-types of the conducting layers form. All radical cation salts of this family can be considered as pseudopolymorphous phases with a general formula of (ET)4[MNOX5]2-xGx (G is a guest solvent molecule, BN or NB). The studied crystals display a range of remarkable structural features such as conformational and charge ordering in the conducting ET layers as well as commensurate and incommensurate structural modulations mainly related to the positional ordering of the components of complex anion layers.
