Cu(Ⅱ) and Ni(Ⅱ) Complexes with 5,5'-Bis(2-acylphenyl)diazo-dipyrromethane: Syntheses, Structures and Properties
摘要:
The reactions of 5,5'-bis(2-acylphenyl)diazo-dipyrromethane (H2L) with CuSO4 and NiCl2 resulted in the formation of corresponding mononuclear coordination complexes 2 (CuL) and 3 (NiL). The crystal of complex 2 is of monoclinic system, space group P21 with a=10.040(5), b=11.900(5), c=11.170(5) Å, β=93.057(8)°, V=1332.8(2) Å3, Z=2, C29H28N6O2Cu, Mr=556.11, Dc=1.386 g/cm, F(000)=578 and μ(MoKα)=0.857 mm-1. The crystal of complex 3 belongs to the monoclinic system, space group P21/n with a=12.0445(6), b=17.2101(8), c=16.3304(6) Å, β=128.407(2)°, V=2654.6(2) Å3, Z=4, C29H28N6O2Ni, Mr=551.28, Dc=1.380 g/cm, F(000)=1152 and μ(MoKα)=0.770 mm-1. In both complexes, the metal ions are in square-planar geometry by coordinating to two azo N atoms and two deprotonated pyrrole N atoms. Intramolecular Cu…O=C in complex 2 and intermolecular Ni…O=C in complex 3 were found. The UV-Vis spectra and thermal stability of complexes 2 and 3 were also studied.
