The reaction of P4E3 (E = S, Se) with NbCl5 yields [β-P4S4(NbCl5)2] and [P4Se3(NbCl5)]. [β-P4S4(NbCl5)2] crystallizes in the monoclinic space group P21/n with the lattice parameters a = 6.226(1), b = 12.971(2), c = 26.380(2) A, β = 93.7(1) (Z = 4). In this compound a sulfur atom is introduced into the basal P3-ring and the resulting β-P4S4 is central unit of the complex. [P4Se3(NbCl5)] crystallizes in the same space group type with the lattice parameters a = 11.939(1), b = 18.603(2), c = 12.763(4) A, β= 90.16(2)° (Z = 8). In both compounds the ligands are coordinated to basal phosphorus atoms.
