A Cu(I) coordination polymer employing a nonsteroidal aromatase inhibitor letrozole as a building block

The reaction of [Cu(I)(MeCN)(4)](BF4) with letrozole (1-[bis(4-cyanophenyl)methyl]-1,2,4-triazole, LTZ) affords a quite unusual 3-D coordination polymer in which for the first time LTZ demonstrates its coordinating ability as a tetradentate ligand.
