A 3D Coordination Framework Based on Linkages of Nanosized Hydroxo Lanthanide Clusters and Copper Centers by Isonicotinate Ligands

Abstract

Nanoscale clusters are of great popularity due to the novel structural characteristics and rich electronic, magnetic, optical, and catalytic properties associated with their quantumsize effects.[1] Although the cluster chemistry of transition metals (TMs) is now well-established and many huge clusters

A New Series of Anhydrous Lanthanide‐Based Octahedral Hexanuclear Complexes

“…[6,13] Up to now only a few coordination polymers with polynuclear lanthanide complexes have been reported. [14][15][16][17] In fact, while the cluster chemistry of d block transition metals is now firmly established, [18,19] analogous chemistry involving lanthanide ions is rather underdeveloped.…”

“…Recently, the design and construction of heterometallic complexes catch more and more attention due to their intriguing topologies and potential applications in, e.g., magnetism,g as storage, luminescent materials [1][2][3][4][5]. As known, the selection of metal centers and organic linkers is an extraordinary vital step in theconstruction of metal-organicframeworks(MOFs).…”

Two 1D Ladderlike Heterometallic Zinc(II) Coordination Polymers: Syntheses, Crystal Structures, and Fluorescence Properties

“…Adopting this synthetic approach, the ligand design strategy is very important in the construction of unusual heterometallic coordination frameworks. [13][14][15][16][17][18][19][20][21][22][23][24][25] However, the design and synthesis of heterometallic polymers are still a challenge to chemists, especially in the cases of 3d-3dЈ heterometallic polymers, because the one-pot synthetic approach can lead to a statistical mixture of homo-and heterometallic architectures. [26,27] The other synthetic approach is given by the "metalloligand" concept, i.e., utilizing a metal complex as ligand to coordinate an appropriate additional metal ion.…”
