Paddlewheel‐Type Dirhodium Tetrapivalate Based Coordination Polymer: Synthesis, Characterization, and Self‐Assembly and Disassembly Transformation Properties

Abstract

An extended one-dimensional chain-type coordination polymer, [Rh 2 (piv) 4 (tpy)] n (1; piv = pivalate, tpy = 2,2′:6′,2′′-terpyridine), has been synthesized and characterized by singlecrystal and powder X-ray diffraction analyses, elemental analysis, IR spectrosopy, thermogravimetric analysis, UV/Vis diffuse reflectance spectroscopy, and magnetic measurements at 300 K. This complex shows unique repeatable self-assembly and

Linear One-Dimensional Coordination Polymers Constructed by Dirhodium Paddlewheel and Tetracyanido-Metallate Building Blocks

“…Many dirhodium molecular complexes have been reported owing to the facility of the rhodium ions to coordinate monodentate donor ligands at the axial positions of the paddlewheel structure [1,2,[14][15][16][17]. Moreover, dirhodium units have been used to form one-dimensional coordination compounds using bridging ligands between the dimetallic cores [18][19][20][21]. The use of other metal complexes as connectors between the paddlewheel units can lead to the formation of heterometallic one-dimensional coordination polymers, whose versatile chemical and physical properties, such as temperature dependent luminescence or modulation of their electronic structures, make those polymers promising materials [22][23][24][25].…”

Dirhodium Coordination Polymers for Asymmetric Cyclopropanation of Diazooxindoles with Olefins: Synthesis and Spectroscopic Analysis

“…The formation of coordination polymers is a feasible strategy to heterogenize dirhodium catalysts (II) as demonstrated by several works. [60][61][62][63][64][65] Very recently, some of us have achieved the heterogenization of dirhodium catalysts by ligand exchange employing ditopic ligands to synthesize dirhodium coordination polymers. [66][67] The structures of these as-obtained 2D coordination polymers were determined by a combination of SEM, XRD and 13 C and 19 F solid-state NMR techniques.…”

Coordination-Induced Self-Assembly of a Heteroleptic Paddlewheel-Type Dirhodium Complex

“…Recently, paddlewheel-type Rh 2 complexes have been utilized as secondary building units (SBUs) for supra-molecular complexes [24,25], such as coordination polymers (CPs) [26][27][28][29][30] and two conventional synthetic strategies for the production of Rh2-SBU-based CPs and MOFs. The first strategy is the ligand-exchange reaction between the equatorial carboxylate ligands of the Rh2 complex precursor and organic poly-carboxylic acids at high temperature [14,[31][32][33][34].…”
