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 ...

catena-Poly[[aqua(2,2′-bipyridine-κ2N,N′)copper(II)]-μ-5-nitroisophthalato-κ3O1,O1′:O3]

open access: yesActa Crystallographica Section E, 2008
In the asymmetric unit of the title compound, [Cu(C8H3NO6)(C10H8N2)(H2O)]n, there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center.

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,

Synthesis, X-ray Structures and Hirshfeld Analysis of Two Novel Thiocyanate-Bridged Ag(I) Coordination Polymers

open access: yes, 2023
Two novel silver(I) coordination polymers, [Ag(4BP)(SCN)]n (1) and {(4BPH)+[Ag(SCN)2]−}n (2) (4BP = 4-benzoyl pyridine), have been synthesized. The two complexes were prepared using almost the same reagents, which were AgNO3, 4BP and NH4SCN.

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.
