The nature of the exchange interactions in three metal-organic coordination networks families is examined. These families have a general form [formula omitted]. Since [formula omitted] molecules are very long, our networks are reduced to effectively one-dimensional chain systems with very weak interchain interaction. The Bonner–Fisher and Fisher classical spin models are applied to fit the magnetic susceptibility data, and results of the fits are discussed. Metal ions inside [formula omitted] and [formula omitted] interact with ferromagnetic interactions and can be described with Fisher classical spin model, while metal ions in [formula omitted] interact with antiferromagnetic interaction and it can be described with the Bonner–Fisher model. Fitting parameter [formula omitted] produced from our models has higher value in [formula omitted] than in [formula omitted] for the same [formula omitted]. It was found that the total spin value is dominant factor to the strength of the magnetic interaction.
