A Novel Hybrid of Bi-Based High-Tc Superconductor and Molecular Complex

Molecular complex Hgl2Py2 (Py = pyridine) was intercalated into the Bi-based high- Tc cuprate by intercalative complexation. The intercalation method adopted in this work is based on the new concept, where a neutral ligating agent is diffused into the preintercalated Hgl2 layer leading to a charge transfertype complex formation between the Bi2O2 double layers of Bi2Sr2CaCu2Oy.
