Cover illustration: 2,6-Diacetylpyridinebis(semicarbazone), DAPSC, is a potential pentadentate ligand that has gained interest in the design of single molecule magnets and as a potential antimicrobial agent in its metal-coordinated form. The room temperature crystal structure of a samarium(III) nitrate complex with DAPSC, tetraaqua[2,6-diacetylpyridine bis(semicarbazone)]samarium(III) trinitrate, is isomorphous with other known lanthanide(III) nitrate complexes with DAPSC. The cations in these structures have four coordinated water molecules such that their coordination geometry is best described as a distorted tricapped trigonal prism. The salts all have three nitrate counter-anions involved in myriad hydrogen bonds with the coordinated water molecules. See: Gioia, Crundwell & Westcott [IUCrData (2017). 3, x181454].
