Chirality transfer refers to the process in which chiral cations compel crystallization of inorganic component into Sohncke group. Enhancing chirality organic-inorganic hybrid metal halides (OIHMHs) through transfer, aimed at improving chiroptical and spintronic properties, remains challenging due complexity underlying mechanism. To investigate this, we propose a novel concept─chirality coefficient─as means quantifying strength OIHMHs. A comparative study OIHMHs with varying dimensionality, ions, centers was conducted elucidate this By analyzing factors such as hydrogen bonding, number centers, helical geometry, structural distortions, found that is influenced by combination dimensions centers. Importantly, our findings reveal 0D, 1D OIHMHs, particularly zigzag chain configuration, exhibit stronger than their 2D counterparts. Moreover, reduction enhances transfer. However, no direct correlation observed between spin splitting. These insights contribute more comprehensive understanding mechanisms provide strategic approach for enhancing associated physical properties
