Of course, this requires a small electronegative coligand, of which F has no superior; but OH, CN, and CCH are also small ligands with high electron affinities.
没有比氟更适于此要求的了。 不过，OH、CN和CCH也都是带有高电子亲合性的小配体。

The one drawback is that the CCH must be obtained through support channels as it is not posted publicly.
缺点在于CCH必须通过支持渠道获取，它不是公开发布的。

A CCH is a hotfix for the client, but instead of just a single fix, we include a set of fixes that multiple customers are asking for.
