Popis:	A new europium ternary complex [Eu2(BTA)6(4,4′-bpdo)]n (HBTA=benzoyltrifluoroacetone, 4,4′-bpdo=4,4′-bipyridine dioxide) is prepared. Crystal analysis shows that it possesses infinite one-dimensional linear chains containing binuclear coordination moieties Eu2(BTA)6(4,4′-bpdo) in which two Eu(III) ions were bridged by two terminal oxygen atoms from two different 4,4′-bpdo molecules. There are two crystallographically distinct Eu2(BTA)6(4,4′-bpdo) units, in which all Eu(III) ions are in the similar EuO8 environments but with different symmetries and twisting angles between pyridine rings. The inter-chain π–π stacking interactions between neighboring phenyl rings in Eu2 chains extend the 1D coordination chains to construct a novel 2D supramolecular architecture, which further stabilizes this structure.
