Syntheses, Structures, and Luminescent Properties of Zinc(Ⅱ) and Silver(Ⅰ) Complexes Based on 1-(4'-Carboxylatobenzyl)-3-(pyrazin-2-yl)pyrazole

         

摘要

Two novel coordination compounds,[Zn(CBPP)2(H2O)2]·3H2O (1) and[Ag(CBPP)·2H2O](2) (HCBPP =1-(4'-carboxylatobenzyl)-3-(pyrazin-2-yl)pyrazole),were hydrothermally synthesized and characterized.Compound 1 crystallizes in monoclinic,space group C2 with a =26.221 (4),b =8.4211(7),c =14.295(3) A,β =114.561(8)°,V =2705.9(2) A3,Dc =1.587 g/cm3,C28H28C12NsO9Zn,Mr =685.97 F(000) =1416,μ(MoKct) =0.926 mm-1,Z =4,R =0.0287,wR =0.1076 for 2818 observed reflections (I> 2σ(I)),and R =0.0300,wR =0.1110 for all data.In 1,each deprotonated CBPP ligand with a bidentate coordination mode connects two Zn(Ⅱ) atoms to generate a 1D helical chain along the b axis.The adjacent chains intersect with each other through hinged Zn(Ⅱ) ions to build up an interesting two-dimensional network.Compound 2 crystallizes in monoclinic,space group P21 with a =6.3544(1),b =11.7195(3),c =19.3188(4) A,β =94.297(2)°,V =1434.64(5) A3,Dc =1.894 g/cm3,C14H13AgN4O4,Mr =409.15 F(000) =816,μ(MoKa) =11.536 mm-1,Z =4,R =0.0456 and wR =0.1184 for 2402 observed reflections (I > 2o(I)),and R =0.0517,wR =0.1275 for all data.In 2,each ligand binds two Ag (Ⅰ) atoms in a tridentate coordination mode to form an infinite zigzag chain.Their thermal and photoluminescent properties were also investigated.
