Iron(II) Spin Crossover Complexes with 4,4′-Dipyridylethyne—Crystal Structures and Spin Crossover with Hysteresis

open access: yesMolecules, 2020
Three new iron(II) 1D coordination polymers with cooperative spin crossover behavior showing thermal hysteresis loops were synthesized using N2O2 Schiff base-like equatorial ligands and 4,4′-dipyridylethyne as a bridging, rigid axial linker. One of

Comparison of radiation shielding properties of some coordination polymers

open access: yesRadiation Protection and Environment, 2019
We have studied the X-ray and gamma radiation shielding parameters such as mass attenuation coefficient, linear attenuation coefficient, mean free path, half-value layer, tenth-value layer, effective atomic numbers, electron density, exposure buildup ...

4,2′:6′,4′′-Terpyridines: diverging and diverse building blocks in coordination polymers and metallomacrocycles [PDF]

open access: yes, 2014
4,2′:6′,4′′-Terpyridine (4,2′:6′,4′′-tpy) is one of the less well documented isomers of the well-established bis-chelating 2,2′:6′,2′′-terpyridine. The N-donors of the outer rings in 4,2′:6′,4′′-tpy subtend an angle of 120°, leading to a description of 4,

Plastic bending in a semiconducting coordination polymer crystal enabled by delamination

open access: yesNature Communications, 2022
Coordination polymers are normally considered to be brittle due to the dominance of directional coordination bonding. Here the authors report the plastic bending in a semiconducting coordination polymer crystal enabled by delamination.

Synthesis of Atomically Precise Single-Crystalline Ru2-Based Coordination Polymers [PDF]

open access: yes, 2020
Methods to incorporate kinetically inert metal nodes and highly basic ligands into single-crystalline metal-organic frameworks (MOFs) are scarce, which prevents synthesis and systematic variation of many potential heterogeneous catalyst materials.
