چکیده

The asymmetric unit of the title compound, 2C18H15Te(+)·2Br(-)·C3H6O or Ph3TeBr·0.5Me2CO, contains two crystallographically independent tri-phenyl-telluronium cations, two bromide anions, and one disordered [site-occupancy ratio = 0.581 (7):0.419 (7)] solvent mol-ecule. Inter-ionic Te⋯Br inter-actions connect the cations and anions into a tetra-meric step-like structure. The primary coordination spheres of both Te atoms are TeC3 trigonal pyramids: three short secondary tellurium-bromine inter-actions expand the coordination geometry of one of the Te atoms to an octa-hedron. While the other Te atom shows only two Te⋯Br secondary bonding inter-actions, it is also six-coordinated due to a Te⋯π inter-action [3.769 (2) Å] with one of the phenyl rings of the adjacent cation.

In the crystal structure of the title compound, [Cu(3)Br(3)(C(26)H(24)P(2))(3)]·0.5CH(3)COCH(3), two of the Cu centers are bridged by two bromide anions forming a Cu(μ-Br)(2)Cu core, which is further bridged by a 1,2-bis-(diphenyl-phosphino)-ethane (dppe) ligand. The third Cu center is terminally bound to another bromide ligand and is connected to the other two Cu atoms by bridging dppe ligands...
