Housecroft, Catherine E.The Royal Society of ChemistryNew Journal of ChemistryChaurin, V.; Constable, E. C.; Housecroft, C. E. What is the coordination number of copper(II) in metallosupramolecular chemistry? New J. Chem., 2006, 30, 1740-1744....
Analysis of structural and solution data shows a specific stabilisation of copper(ii) in ternary complexes containing one 2,2′:6′,2″-terpyridine and one 2,2′-bipyridine ligand. This is not a general phenomenon relating to five-coordinate copper(ii), but rather a specific consequence of th...

One of the interests in building coordination polymers is the creation of new tuneable functional materials. In this part of the review, we will present examples of how metal-organic frameworks are promising as materials for applications in gas storage, anion exchange (due to the porosity and zeo...
Although the 1,9 coordination is most commonly attributed to aluminum–alizarin lakes, in 1994, Wunderlich et al. obtained an X-ray structure of a dimeric complex [{Al(L)2(μ-OH)(μ-Ca)}2], L = aliz2−, where the aluminum atom occupies both phenolate (1,2) positions [26]. The...
Some of the dyes are made of materials that change color to show how acidic or basic a chemical is. Picture the smell Foamazol chemical blowing agents for use in most application such as structural foam, wire and cable, profile and sheet, blown and extruded films, blow molded containers, ...
Old ideas from Signal Processing, Neuroscience, and Physics get a new life.Graph signal processing is considered by many the spark that re-ignited the recent interest in Graph ML and provided the first set of tools such as generalised Fourier transforms and graph convolutions. Other fundamental ...
