Palacios MA, McLellan R, Beavers CM, Teat SJ, Weihe H, Piligkos S, Dalgarno SJ, Brechin EK.
PMID: 26121216
Chemistry. 2015 Jul 27;21(31):11212-8. doi: 10.1002/chem.201500001. Epub 2015 Jun 29.

The central Mn(II) ions in a series of calix[4]arene-stabilised butterflies can be sequentially replaced with Ln(III) ions, maintaining the structural integrity of the molecule but transforming its magnetic properties. The replacement of Mn(II) for Gd(III) allows for the examination...

A diplatinum(II) complex was prepared from a new 1,2-dithienylethene-based ligand containing N-methylimidazole groups as metal-binding units. Reaction of the ligand 1,2-bis[2-methyl-5-(1-methyl-1H-imidazol-2-yl)-3-thienyl]-cyclopentene (L2(H)) with cis-dichlorobis(dimethylsulfoxido)platinum(II) generated the bimetallic complex trans-[Pt2Cl4(DMSO)2(L2(H))] (DMSO = dimethyl sulfoxide), whose DNA-interacting properties were investigated using...
