Rademeyer, Melanie; Liles, David C. (International Union of Crystallography, 2010)A fundamental understanding of the role of oxyanion geometry on molecular packing and non-covalent interactions in salt crystal structures is central to the fields of both molecular recognition and crystal engineering. The ...

Landman, Marile; Barnard, Werner; Van Rooyen, Petrus H.; Liles, David C. (Elsevier, 2012-08)The carbine complex [MnCp(CO)2C(OEt)(TT)], (TT = 3,6-dimethylthieno[3,2-b]thiophene) 1, was synthesized according to the classical Fisher method. The novel complex was fully characterized using various spectroscopic ...
