Greg Powell, Pruitt Professor of Chemistry at Abilene Christian University, Abilene, Texas, visited in March, 2019. We had a great time working on crystal structures and discussing chemistry.
Greg's group at Abilene is currently making large assemblies with metal-metal bonds.

IN THE FALL-2018 AMERICAN CRYSTALLOGRAPHIC ASSOCIATION NEWSLETTER
available here:
https://www.amercrystalassn.org/assets/RefleXions/ACA%20Fall%202018.pdf
on Pages 51 - 52 there is a report on the session "Crystallography in Synergy with Computation, Sectroscopy and Synthesis," which was organized by Alberto Albinati and Larry Falvello and presented at the ACA annual meeting in July.
IN ADDITION to a very intersting talk by Milagros Tomás (3rd from the right), we had the pleasure of hosting an invited lecture by Joel Bernstein (4th from left), who gave a fascinating history of molecular crystal chemistry, interwoven with his own experiences as a leading researcher in this field.
Joel's recent passing is sadly lamented. He leaves behind contributions of inestimable importance to chemical crystallography.

{Ni-Ln} Series of Heterodinuclear Complexes Based on Schiff Base Ligand and Their Dehydration
Anna's oral presentation at "Progress in Inorganic Chemistry" (PANCH2018) in Levoča.
Transition-metal hydroxy clusters with a heretofore unobserved core geometry have been synthesized by combining platinum centers with two different oxidation states and their corresponding different coordination indices and geometries.
On-line in Chem. Comm. -- See two new organometallic compounds with brand-new transition-metal hydroxide core geometry. This unexpected result shows that there is still new chemistry to be discovered in this long-studied family of compounds.
