Effects of Concurrent Sulphur‐ and Phosphorus Incorporation in Nickel Cyclam‐based Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Accepted Article.
We investigated the concurrent presence of S, P, and N donor atoms in isocyclam frameworks and their corresponding nickel complexes to get insight into the influence of these different heteroatoms on their structural and electronic properties. Structural elucidation of the complexes revealed both octahedral and square‐planar coordination modes for Ni ...

Synthesis and Structure–Activity Relationship of Porous Coordination Polymers and Their Composites as Photocatalysts: Environmental Remediation

open access: yesElectron, EarlyView.
Porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) hold promise as photocatalyst candidates for the remediation of toxic metal ions and organic pollutants. However, they often exhibit inferior removal and catalytic efficiency due to the rapid recombination of photoexcited electrons and holes.

Synthesis and characterisation of ferrocenyl-phosphonic and -arsonic [PDF]

open access: yes, 2001
The ferrocene-derived acids FcCH₂CH₂E(O)(OH)₂ [4, E=P; 10, E=As; Fc=Fe(η₅-C₅H₅)(η⁵-C₅H₄)] have been synthesized by the reaction of FcCH₂CH₂Br with either P(OEt)₃ followed by hydrolysis, or with sodium arsenite followed by acidification.
