摘要	A Peierls-extended Hubbard model is used to study the possible high-spin ground state of a quasi-one-dimensional organic-inorganic bipartite lozenge ferrimagnetic chain. Considering the electron-phonon (e-ph) coupling and electron-electron (e-e) interaction, the distribution of charge density, the ferrimagnetic order and the stability of the high-spin ground state are studied in detail. It is shown that the nearest-neighboring Coulomb repulsion leads to the transfer of the charge density and spin density between sites A and B, and the spin density is modulated by the charge density. The on-site e-e interaction makes the antiferromagnetically correlated distribution of spin density along the chain stronger while the e-e repulsion between the nearest-neighboring sites makes it weaker.
