Zusammenfassung: 
The reaction of P4E3 (E = S, Se) with NbCl5 yields [beta-P4S4(NbCl5)(2)] and [P4Se3(NbCl5)]. [beta-P4S4(NbCl5)(2)] crystallizes in the monoclinic space group P2(1)/n with the lattice parameters a = 6.226(1), b = 12.971(2), c = 26.380(2) Angstrom, beta = 93.7(1) (Z = 4). In this compound a sulfur atom is introduced into the basal P-3-ring and the resulting beta-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) Angstrom, beta=90.16(2)degrees (Z = 8). In both compounds the ligands are coordinated to basal phosphorus atoms.
