Symmetry Breaking and Cooperative Spin Crossover in a Hofmann-Type Coordination Polymer Based on Negatively Charged {Fe^II(μ₂-[M^II(CN)₄])₂}_n^2n- Layers (M^II = Pd, Pt).

ABSTRACT: We report herein the synthesis and characterization of two unprecedented isomorphous spin-crossover two-dimensional coordination polymers of the Hofmann-type formulated {Fe^II(Hdpyan)₂(μ₂-[M^II(CN)₄])₂}, with M^II = Pd, Pt and Hdpyan is the in situ partially protonated form of 2,5-(dipyridin-4-yl)aniline (dpyan). The Fe^II is axially coordinated by the pyridine ring attached to the 2-position of the aniline ring, while it is equatorially surrounded by four [M^II(CN)₄]^2- planar groups acting as trans μ₂-bidentate ligands defining layers, which stack parallel to each other. The other pyridine group of Hdpyan, being protonated, remains peripheral but inv
