LaZnB5O10, the first lanthanum zinc borate
Abstract
Lanthanum zinc pentaborate, LaZnB5O10, was synthesized by flux-supported solid-state reaction. It is a member of the LnMB5O10 (Ln = rare earth ion and M = divalent metal ion) structure type. The crystal shows a three-dimensional structure constructed from two-dimensional {[B5O10]5−}n layers with the lanthanum (coordination number nine) and zinc (coordination number six) ions filling in the interlayers.
