19 Claims

1. An organic-inorganic hybrid complex, formed from basic units represented by formula (I) being periodically assembled in at least one spatial direction:

[L_x-i□i][M_aC_b].A_z (I)

wherein in the formula (I),

M represents a metal element of the first transition series,

C represents an atom, atomic group, or anion optionally forming a metal cluster with M,

L represents an organic bridging ligand forming a coordination bond with the metal M or metal cluster M_aC_b,

□ represents a ligand defect,

A represents an atom or cation capable of being intercalated and de-intercalated,

x is a number of 1-4, more optionally a number of 1-3,

a is a number of greater than 0 and less than or equal to 4, more optionally a number of 1-4,

z is a number of 0-2, more optionally a number of 0-1,

0<i<x, and 0≤b:a≤1,

wherein the defect level of the organic-inorganic hybrid complex is expressed in a defect percentage, i/x*100%, which is 1% to 30%.
