Additions and Corrections 1999, Volume 18 Guo-Xin Jin,* Yanxiang Cheng, and Yonghua Lin: Synthesis and X-ray Structure of a Highly Symmetrical Selenium-Centered Hexanuclear Neodymium Complex, [Cpt6Nd6Se13]- (Cpt ) η5-ButC5H4). Page 947. The X-ray crystal structure of the title complex was incorrectly reported to have Z ) 2 with a molecular formula of [Na(thf)6][Cpt6Nd6Se13]. The cluster anion is situated on a crystallographic inversion center with the countercation located in a general position, giving an overall composition of [Na(thf)6]2[Cpt6Nd6Se13] and Z ) 1. Apart from this error, the crystal structure data are essentially correct (an updated table of X-ray crystallographic data collection and refinement parameters are given in the Supporting Information). This correction, however, calls into question the magnetic data for this compound, which is now formulated correctly as an even-electron dianion.
