Abstract
The structure of the title compound has been determined by the heavy-atom method from 765 reflections, measured with a diffractometer, and refined by full-matrix least-squares methods to R 0.033.Crystals are orthorhombic, space group Pmnb, a= 9.37(1), b= 7.96(1), c= 10.93(1)Å, Z= 4. In the discrete molecules of the complex a tellurium atom is bonded to one bivalent pentane-2,4-dione ligand via the two α-carbon atoms [Te-C 2.168(5)Å, C–Te–C 86.4(2)°]. This structure is the first to be reported wherein a pentane-2,4-dione ligand binds in this manner. All hydrogen atoms have been located and refined. There is no evidence for any hydrogen-bonding between the molecules.Keywords
