摘要：

The radical anion salt of TCNQ (7,7,8,8-tetracyanoquinodimethane) with the trans-[Ru(ox)(en)(2)NO](+) cation (ox=oxalate, en= ethylenediamine), namely {trans-[Ru(ox)(en)(2)NO]}(2)(TCNQ)(3), was synthesized by slow diffusion method from water solution of trans[Ru(ox)(en)(2)NO]Cl and of LiTCNQ. An X-ray structure analysis indicates that the cation: anion ratio of the obtained complex is 2:3. Two of three TCNQ molecules are stacked along the a direction to form columnar structure. Between these columns the remaining TCNQ molecules are inserted with their long molecular axis along a direction. Several -(NHN)-H-...-type hydrogen bonds between nitrile groups of TCNQ molecules and ethylenediamine ligands of trans- [Ru(ox)(en)(2)NO](+) cation, and -(OHN)-H-...-type hydrogen bonds between oxygen atoms of oxalate ligands of trans- [Ru(ox)(en)(2)NO] + cations and ethylenediamine ligands of neighboring trans- [Ru(ox)(en)(2)NO] + cations are observed. The room temperature electrical conductivity of {trans-[Ru(ox)(en)(2)NO]}(2)(TCNQ)(3) is < 10(-6) S cm(-1) (c) 2005 Elsevier B.V. All rights reserved.
