Templation of a square grid copper(ii) 4,4′-bipyridine network by a 3D PtS-related Cu(i)–Cu(ii) 4,4′-bipyridine crystal

Abstract

Two cationic networks, [Cu(I)Cu(II)(4,4'bipy)4(H2O)2](3+) and [Cu(II)(4,4'bipy)2(H2O)2](2+) have been formed from a solution in which Cu(I) undergoes aerial oxidation. Whilst the topologies of the two networks are different the arrangement of Cu centres is almost identical, a structural feature which presumably allows for [Cu(I)Cu(II)(4,4'bipy)4(H2O)2](3+) to serve as a crystalline template for [Cu(II)(bipy)2(H2O)2](2+).

Synthesis and Structural Studies of Three‐Dimensional Supramolecular Motifs Derived from Neutral and Cationic Zinc Alkanesulfonates

“…These interactions result in the transformation of the layered coordination assembly into a 3D supramolecular motif (Figure ). Thus, the structure closely resembles a few reported examples of zinc–bipy coordination assemblies , …”

Site-specific growth of MOF-on-MOF heterostructures with controllable nano-architectures: beyond the combination of MOF analogues

“…For example, anisotropic hybridization of single-crystalline MOFs via faceselective epitaxial growth was reported for asymmetric MOF-on-MOF heterostructures. [40][41][42] Recently, Oh's group reported isotropic and anisotropic growth of secondary MOFs on a presynthesized MOF template to form MOF-on-MOF with controllable nanostructures. 32 However, in these reports, guest MOFs have been grown on their analogues as the host with either the same metal ions or ligands via epitaxial growth, limiting the structural and compositional diversity of MOF-on-MOF hybrids.…”

Construction of Two High‐Nuclear 3d‐4d Heterometallic Cluster Organic Frameworks by Introducing a Bifunctional Tripodal Alcohol as a Structure‐Directing Agent

“…The size of the large channelsi sa bout 1.13 1.44 nm 2 ,w hile that for the smallc hannels is about 0.68 1.05 nm 2 .I na ddition, there are additional four-connected Cu + ions insert into the diagonal positions of half of four-membered windowsg enerated by interconnecting four Cd 5 Cu 6 clusters in ac plane ( Figure S5), which is helpful to furthers tabilize the porouss tructure. The Cu + ions were formed by in situ reduction of Cu 2 + ions under solvothermal conditions, [16] and the oxidation state was testified by BVS calculation (Table S2)a nd XPS characterization ( Figure S2b). So far,t he number of frameworks based on Cd-Cu heterometallic clusters is no more than 5, [17] half of whicha re from our group, althoughh undreds of heterometallic MOFs can be found in CCDC database.…”
