title: Tris(thio-cyanato-κN)tris-(triphenyl-phosphine oxide-κO)europium(III)-(nitrato-κ(2) O,O')bis-(thio-cyanato-κN)tris-(triphenyl-phosphine oxide-κO)europium(III) (1/1).
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 Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-action between the phenyl rings of the two mol-ecules [centroid-centroid distance = 4.138 (4) Å].
