Copper(II) Carboxylate Containing Paddle Wheel Structure: Synthesis and Crystal Structure

Abstract

. The Cu(II) complex is a cocrystal containing two inorganic units. Each Cu(II) adopted square pyramidal geometry.

Air‐Free Synthesis of a Ferrous Metal‐Organic Framework Featuring HKUST‐1 Structure and its Mössbauer Spectrum

“…In this context, iron(II) is especially attractive because of its potential redox chemistry and ability to activate molecular oxygen. Moreover, the bimetallic paddlewheel structure found in HKUST‐1 MOF materials bears a strong resemblance to the dinuclear centers found in oxygenase enzymes . Iron(II)‐based MOFs have been considered previously, although unequivocal evidence for the formation of an iron(II) HKUST‐1 analog in the form of single‐crystal X‐ray diffraction paired with Mössbauer spectroscopy is lacking , .…”

“…Moreover, the bimetallic paddlewheel structure found in HKUST-1 MOF materials bears a strong resemblance to the dinuclear centers found in oxygenase enzymes. [26] Iron(II)-based MOFs have been considered previously, although unequivocal evidence for the formation of an iron(II) HKUST-1 analog in the form of singlecrystal X-ray diffraction paired with Mössbauer spectroscopy is lacking. [27,28] In this contribution, we demonstrate an airfree synthesis of the HKUST-1 analogue Fe 3 (BTC) 2 (1) and provide evidence for its formulation as a bona fide iron(II)-MOF by Mössbauer spectroscopy.…”
