Abstract

Two new heterometallic coordination polymers, [Dy(TPA)Fe(CN₆)(H₂O)₂]·4H₂O (1-Dy) and [Gd₂(TPA)₂Fe₂(CN₆)₂(CH₃OH)₂]·8.5H₂O (2-Gd) were synthesized by reacting DyCl₃·6H₂O with K₃[Fe(CN)₆] and tri[(2-pyridyl)methyl]amine (TPA). The structures of both complexes were established by single crystal X-ray diffraction. Polymer 1-Dy exhibits a one-dimensional (1D) chain structure formed by [Fe(CN)₆]³⁻ bridging the [Dy(TPA)(H₂O)₂]³⁺ units. For polymer 2-Gd, each [Fe(CN)₆]³⁻ unit is connected to three [Gd(TPA)(CH₃OH)]³⁺ units through three nearly coplanar CN groups, forming a near-rectangular grid Gd₂Fe₂. These Gd₂Fe₂ extend to generate a 2-dimensional (2D) monolayered topology, which represents a cyclic formation of a novel grid structure. Hydrogen bonding interactions via water molecules stabilize both structures. Magnetic susceptibility measurements indicate weak antiferromagnetic interactions between Ln(III) and Fe(III) ions, with Fe(III) and Ln(III) centers behaving as nearly isolated magnetic entities.

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
