A theoretical model is given to deal with two neighboring organic ferromagnetic chains including the inter-site electron-electron interaction. The results show that when the inter-site e-e interaction is greater than a critical value, which varies with the interchain coupling, there exists charge density wave(CDW) along the main chain. When the interchain coupling increases to a critical value, the CDW disappears and the spin density redistributes. The interchain coupling stabilizes the ferromagnetic state while the inter-site e-e interaction makes it unstable.
