Abstract
We studied the structural and physical properties of the hypervalent system Ba2Bi(Sb1-xBix)2 (0 ¯ x ¯ 1) with an anisotropic "square-honeycomb" layer. We found that the orthorhombic Ba2BiSb2 (x = 0) shows a charge density wave (CDW) transition at approximately 230K accompanied by a significant elongation of the b-axis, indicating the quasi-one- dimensional nature along the b-axis in its electronic state, as supported by first-principles calculations. This CDW transition is rapidly suppressed with increasing x, leading to the appearance of superconductivity for 0.375 ¯ x ¯ 1. The superconducting transition temperature Tc increases slightly with x and the maximum Tc was 4.4K for Ba2Bi3 (x = 1). © 2014 The Physical Society of Japan.
