New Paper published in Dalton Transactions

Graphical Abstract

Structure of the tetrameric [Zn4(L)4]8+ cation investigated in the work.

Congratulations to Dawn, Chris, Bjørn and Joe for their recent paper in Dalton Transactions titled “A folded [2 × 2] metallo-supramolecular grid from a bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand“. In this work, a new flexible bis-tridentate donor ligand containing 1,2,3-triazolyl-picolinamide (tzpa) binding sites was developed, which contained structural elements from two of the group favorites 2,6-dipicolinamide (dpa) and 2,6-bis-(1,2,3-triazolyl)pyridine (btp). The new ligand was then used in the formation of a tetranuclear grid with Zn(II) or Fe(II) ions, which was probed with X-ray diffraction, NMR, UV-Visible spectroscopy and mass spectrometry. It also involved a productive collaboration with Dr Manuel Reuther and Dr John O’Brien from the NMR Spectroscopy Facility in TCD, who provided help in understanding the solution behavior of the material using the T1 spin-lattice relaxation parameter in 1H NMR spectroscopy.
