First of all I am interested in the data on crystal structure of yttrium lactates or basic lactates (to be more precise, D-lactates). Surprisingly, I did not find any data in single crystal databases. Any information on crystalline rare earth lactates will be also helpful.
Thanx a lot!
Dear Alexander E. Baranchikov many thanks for this interesting technical question. It appears that crystalline yttrium lactates have not yet been reported. i did a SciFinder search on this topic and found only three articles in which the complexation of yttrium with lactate was studied in solution. Cited below is a typical example.

Dear Alexander E. Baranchikov there is some more information in the literature about structurally characterized rare-earth metal lactate complexes. Here are some references which I found:
1. Luminescence of unique 1D tube-like lactate lanthanide coordination polymers

2. Bidentate lactate binding in aqueous solution in a cationic, heptadentate lanthanide complex: an effective chiral derivatising agent

Dear Prof. Frank T. Edelmann, thank you for providing the references. Specifically, J. Organometal. Chem. is very interesting. Hope, our single-crystal diffraction experiments (now in process) will result in new rare-earth lactates.
