摘要：

Five polymer-metal complexes of iron(II), cobalt(II), nickel(II), copper(II) and zinc(II) were prepared from the reaction of dithiooxamide with metal salts. Elemental analysis, W-VIS and IR investigations were carried out for the polymer complexes. The temperature variation of the DC electrical conductivity was measured in the range 298-498 K for the five polymer complexes. The proposed mechanism for the Variation is based on defects: quasi-particles, solitons and polarons. (C) 2001 Elsevier Science Ltd. All rights reserved.
