Our model enables us with a tool ideal for detailed analysis of impurity assisted chain formation, where zigzag bonds play an important role. In particular we focus on H (s-like) and O (p-like) impurities and assume, for simplicity, that the presence of impurity atoms in experiments results in ..M-X-M-X-... (M: metal, X: impurity) chain structure in between the metallic leads.
