Journal ArticleDOI
Anion Induced Formation of Supramolecular Associations Involving Lone pair−π and Anion−π Interactions in Co(II) Malonate Complexes: Experimental Observations, Hirshfeld Surface Analyses and DFT Studies
Prankrishna Manna,Saikat Kumar Seth,Amrita Das,Joanna Hemming,Richard Prendergast,Madeleine Helliwell,Somnath Ray Choudhury,Antonio Frontera,Subrata Mukhopadhyay +8 more
TL;DR: A thorough analysis of Hirshfeld surfaces and fingerprint plots facilitates a comparison of intermolecular interactions in 1-3, which are crucial in building supramolecular architectures, and a very interesting feature regarding the role of counteranions has emerged.
Journal ArticleDOI
The chemical vapor deposition of nickel phosphide or selenide thin films from a single precursor
Arunkumar Panneerselvam,Mohammad Azad Malik,Mohammad Afzaal,Paul O'Brien,Madeleine Helliwell +4 more
TL;DR: Nickel phosphide, nickel selenide thin films and their heterostructure were deposited from a newly synthesized single source precursor {Ni[iPr2P(S)NP(Se) iPr2]2 just by altering the deposition temperature using CVD.
Journal ArticleDOI
Ultra-remote stereocontrol by conformational communication of information along a carbon chain
TL;DR: St stereocontrol is demonstrated over a reaction taking place more than 20 bond lengths from the controlling centre, corresponding to a linear distance of over 2.5 nm, providing a chemical model of allostery and might serve as a molecular mechanism for communicating and processing information.
Journal ArticleDOI
Heme-like coordination chemistry within nanoporous molecular crystals
TL;DR: It is reported that a derivative of iron phthalocyanine, a close analog of heme, forms millimeter-scale molecular crystals that contain large interconnected voids and bind N2 at the equivalent of the heme distal site through a SCSC process characterized by x-ray crystallography.
Journal ArticleDOI
Synthetic and structural studies of cobalt-pivalate complexes.
Guillem Aromí,Andrei S. Batsanov,Paul Christian,Madeleine Helliwell,Andrew Parkin,Simon Parsons,Andrew A. Smith,Grigore A. Timco,Richard E. P. Winpenny +8 more
TL;DR: The synthesis and characterisation of a range of cobalt pivalate cage complexes are reported, and a scheme is proposed to account for the many structures observed, which may be applicable to other polymetallic cage complexes.
