This bibliographic review summarises the coordination chemistry of mono- and di-selenium analogues of metal dithiocarbamate ligands, [RR′NCS2]−, as revealed by X-ray crystallography and spectroscopy (77Se NMR and infrared). The Se-ligands are usually chelating but, bridging modes, up to μ4, are known. Reflecting the larger size, greater polarisability and presence of a polar-cap (σ-hole), selenium atoms are more likely to be involved in secondary-bonding (chalcogen-bonding) than sulphur when a competition exists. Isostructural relationships are established across the series in about one-third of the structures.

金属二硫代氨基甲酸酯的单硒和二硒类似物的分子和超分子化学
这份书目评论总结了金属二硫代氨基甲酸酯配体[RR'NCS 2 ] -的单硒和二硒类似物的配位化学,如X射线晶体学和光谱法(77 Se NMR和红外)所揭示。塞-配体通常螯合剂但是,桥接模式下,高达μ 4,是已知的。反映出更大的尺寸,更大的极化率和一个极性帽(σ孔)的存在,当存在竞争时,硒原子比硫更可能参与硫的二次键合(硫族元素键)。整个系列中约三分之一的结构建立了同构关系。
