Situation due to Covid19

We finance our association through the organization of scientific meetings, but due to the Covid crisis two meetings that should take place in 2020, were cancelled, together with the articles that should be published in the proceedings of these events. This is the reason why the flux of published articles has gone down and the closing of volume 5 has been delayed. Happily, we had the project to publish a book "Perovskites and other Framework Structure crystalline materials", and this book is now available in Amazon, Google Books and through distributors and retailers related with Lulu. Chapters are also freely available in the site of the journal.
