Discrete and infinite metal–organometallic coordination networks consisting of europium(III) nodes and quinone π-complexes as spacers

The reaction of the organometalloligand [(η4-benzoquinone)Mn(CO)3]− (p-QMTC) with Eu3+ nodes has been utilized to generate the discrete and polymeric supramolecular metal–organometallic coordination networks [Eu(DMSO)(NO3)2(p-QMTC)2]2 (1) and the polymeric [Eu(p-QMTC)3]∞ (2). The X-ray structures of 1 and 2 are reported.
