Abstract

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu3+ ion. As a result, the nitrate-containing molecule contains disorder of its bidentate nitrate and two N-bound thiocyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking interaction between the phenyl rings of the two molecules [centroid-centroid distance = 4.138 (4) Å].
