描述了通过与混合 O4X2-供体大环配体(X = O、NH、S 或 Se)配位而稳定的几种不寻常的镱 (ii) 配合物。从中性 [YbI2([18]aneO4Se2)] 的晶体结构可以明显看出扭曲的 8-配位,形成第一个报道的 Yb(ii)-硒醚配位实例。
Several unusual complexes of ytterbium(ii) stabilised by coordination to mixed O4X2-donor macrocyclic ligands (X = O, NH, S or Se) are described. Distorted 8-coordination is evident from the crystal structure of the neutral [YbI2([18]aneO4Se2)], forming the first reported example of Yb(ii)-selenoether coordination.
