TL;DR: In this article, two distinct coordination geometries are found in the structures of Cd(S 2 COR) 2 (2,2'-bipyridine) and R = CH 2 CH 2 OCH 3.
Abstract: Two distinct coordination geometries are found in the structures of Cd(S 2 COR) 2 (2,2'-bipyridine). For R = CH 2 CH 2 OCH 3 (1) a N 2 S 2 donor set defines a distorted tetrahedral geometry for cadmium as the xanthate ligands adopt a monodentate coordination mode. By contrast, a N 2 S 3 donor set is found in the structure where R is butyl (2) as one of the xanthate ligands is chelating. An analysis of the crystal structures shows that both lattices feature extensive C-H...π interactions and that in (1) there are C-H...O interactions that are not present in (2). In (2) there are π...π interactions that are absent in (1). A qualitative argument based on crystal packing considerations is proposed to explain the differences in molecular structures.

TL;DR: In this paper, four metal complexes with the general formula [M (L)2(H2O)x] have been synthesized and characterized using elemental analyses, spectral analyses (IR, UV-vis, MS, 1H-NMR), thermal analyses, conductance and magnetic measurements.

TL;DR: This work provides an interesting metalloligand method not only to induce the spa-tial growth of metallic clusters to achieve highly symmetric structures, but also to enhance their stability which is crucial for future application.
Abstract: A series of increasingly large silver nanoclusters with a varied combination of Archimedean and/or Platonic solid arrangements was constructed using a flexible trifurcate TiL3 (L = Salicylic acid o
