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.
描述了通过与混合的O 4 X 2-供体大环配体(X = O,NH,S或Se)配位而稳定的几种unusual(II)异常配合物。从中性[YbI 2([18] aneO 4 Se 2)]的晶体结构中可以明显看出扭曲的8-配位,形成了第一个报道的Yb(II)-硒醚配位的例子。
