Synthesis and Crystal Structure of Trinuclear Copper(I/II) Complex[Cu(pa)2][Cu(pht)2]2

摘要

A novel trinuclear copper(I/II) complex [Cu(pa)2][Cu(pht)2]2 (pa =l,3-propylenediamine, Hpht = 5,5-diphenylhydantoin, i.e. phenytoin) has been synthesized under hydrothermal condition and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The tricnuclear Cu(I/TI) complex is triclinia space group Pi, with a = 8.6506(12), b = 11.8844(16), c = 15.367(2) A, α = 98.5940(10), β = 92.2810(10), γ= 104.188(2)°, Z =1, D_c = 1.478 g/cm~3, μ = 1.115 mm~(-1), the final R = 0.0812 and wR = 0.2029. The complex consists of an interesting trinuclear copper(I/II) unit. In the crystal structure, each Cu(I) ion is linearly coordinated by N2 and N4 from two different 5,5-diphenylhydantoin, respectively and the six coordinated Cu(II) ion adopted a distorted octahedral geomety.
