<jats:title>Abstract</jats:title> <jats:p>Treatment of anthracenebisresorcinol 1 (a tetraphenol) with La(OiPr)3 in THF affords an amorphous 1:2 (14− to La3+) coordination polymer (La host). It catalyzes typical base-promoted reactions such as Michael, nitroaldol, and, less effectively, aldol reactions, where the insoluble catalyst (La host) can be readily recovered and repeatedly used.</jats:p>
