Feb 4, 2018 at 17:10 | comment | added | Abhigyan | @Ayushmaan I found the answer to your question regarding whether beryllium forms complexes or not. It turns out, beryllium is able to form complexes of various types, and has a strong tendency to do so. However, it is unable to form the "hexa" ammoniate because it's maximum coordination number is 4, and can't be extended to 6. What I wrote about the alkali metals (group 1) still stands the same. | |

Oct 7, 2017 at 0:54 | comment | added | Abhigyan | @Ayushmaan I agree with your point, but sadly, I don't have any way of providing you an answer for this. I've looked through just about any textbook I could find, but most of them are copied off either from Concise Inorganic Chemistry or off Inorganic Chemistry: Principles of Structure and Reactivity. P. Bahadur's book is a little different, but as per that book, beryllium forms various complexes. Therefore, I'm truly unaware... And I'm really sorry | |
Oct 6, 2017 at 17:45 | comment | added | Ayushmaan | @abhigyan According to your answer, the group 1 metals won't form complexes due to their large size and lower charge density. But, the second book(Principles of…) explicitly states that beryllium won't form the complex with ammonia, which seems a bit contradictory to me. | |
Oct 6, 2017 at 9:17 | comment | added | Ian Bush | To add to this Eu and Yb, which form reasonably stable 2+ ions, form blue solutions in ammonia which according to doi.org/10.1016/0022-5088(69)90184-2 decompose to the amide and imide. So while I can't quickly find a reference to the hexa-ammoniates it is consistent with the above as Eu and Yb are smaller than Ba, and Eu2+ and Yb2+ are smaller than Ba2+. Other lanthanides dissolve in NH3 to form blu solutions, but after a full 5 minutes searching I can't find decomposition products for Sm in particular. | |
