A new one-dimensional helical complex from the coordination of m-xylylene dicyanide with silver (I) perchlorate

摘要

Crystallization of m-xylylene dicyanide (C_(10)H_8N_2) with AgCO_4 from methanol solution at - 10 deg C affords columnar colorless crystals of [Ag (C_(10)H_8N_2)Cl_4]_n with high yield. The compound structure was confirmed by X-ray crystallography, indicating that its structure features the characteristics of the helical infinite chain along b axis. The 'HNMR and IR spectrum shows that multiplet can be indexed to the proton peaks and the v(Ph-H) and v(C-H) bands of the m-xylylene dicyanide, respectively. Furthermore, the stability behavior of the [Ag(C_(10)H_8N_2)C1O_4]_n is investigated to present that the tiled compound is stable at below 250 deg C. 2005 Elsevier B.V. All rights reserved.
