Novel anion-tunable structural diversity and new topologies in CuII complexes of a Schiff base

Dangling and Hydrolyzed Ligand Arms in [Mn3] and [Mn6] Coordination Assemblies: Synthesis, Characterization, and Functional Activity

“…This recorded a separation of 3.181(5) Å for O12–Mn1 and O12*–Mn1*. This long separation thus prevented the possibility for further deprotonation from μ 3 -OH groups and resulting in the formation of a {Mn 4 (μ 4 -O)} complex as seen in Cu II -carboxylate chemistry. , Within the {Mn 4 (μ 3 -OH) 2 } butterfly core the Mn3···Mn4 separation is shortest at 2.820 Å compared to known reports for triangular fragments . The other manganese centers are separated from each other by the distances falling in the range from 3.414 to 3.647 Å (Figure S6).…”

A family of [Cu2], [Cu4] and [Cu5] aggregates: alteration of reaction conditions, ancillary bridges and capping anions

“…1 Design and synthesis of coordination aggregate complexes, formed by the incorporation of a group of Cu 2 -fragments, is dependent on the choice and selection of the ligand system giving ligand anion bound {Cu 2 L} species in solution. Collapse of two such {Cu 2 L} fragments provides structurally different [Cu 4 ] aggregates having cubane, 8 tetrahedron, 9 steppedcubane, 10 rhomboid, 11 and double-cubane 12 aggregates. 13 From the functional behavior and application point of view the synthesized copper (II) complexes of phenol based multiple alcohol side arm bearing ligand system can be examined for their biomimetic catalytic oxidation efficiency 14 and biophysical studies.…”
