This study reports the intercalation of pyridine molecules between neighboring layers of two-dimensional (2D) ferrous nitroprusside. In the material under study, the stacking of neighboring layers results in the formation of a long range ordered solid, where the 3D structure is supported by dipoledipole attractive interactions between neighboring pyridine molecules in the interlayer region. No chemical interactions were observed between layers, which preserve their identity as a 2D material. In this hybrid inorganic-organic solid, a thermal induced spin transitions from high to low spin on cooling and [a] 4967 [a] The values of δ are reported relative to sodium nitroprusside at 300 K; The fitting error for δ and Δ is no higher than 0.001 mm/s, and it remains below 0.01 mm/s for the value of Γ; Py =pyridine; LS = low spin; HS = high spin.

From the intercalation of 4-substituted pyridine derivatives in 2D ferrous nitroprusside, a series of hybrid inorganic–organic solids with thermally induced spin crossover results.
