摘要

All iron-based superconductors, regardless of their detailed crystal structure, share the same conductive Fe2X2(X=As, P, Se, and S) layers as the crucial structural unit [1-8]. In the Fe2X2layers, edge-shared FeX4tetrahedra form a square lattice in quasi-two-dimensional (quasi-2D) planes. One may wonder what kind of properties will be manifested in the quasi-one-dimensional (quasi-1D) counterparts exhibiting an identical coordination as the above-mentioned quasi-2D cases. Theoretical proposals on magnetic states and possible superconductivity have been reported in the recent five years[9-11].
