It crystallizes in orthorhombic Pbca with a= 16. 201 (5), b=10. 513 (4), c=9. 992(4) A, V=1701. 8(7) A ̄3, Z=4, D_c=1. 888 g/cm ̄3, μ=49. 5 cm ̄(-1) (MoKa),F(000) = 972. The final R and Rto are 0. 039 and 0. 047 for 1052 observed reflections with I≥3σ(I). The result of X-ray structure determination shows that 3hydroxyl-1,5-diazacyclooctane forms a 2 :1 complex with CuBr_2 in which the central copper ion is sandwiched between the two ligands.展开更多
