Hydrothermal Synthesis,Crystal Structure and Thermal Stability of the Complex [Zn(p-ABA)_2(phen)·(H_2O)]·H_2O

The title complex has been synthesized with p-acetamidobenzoic acid and 1,10-phenanthroline(phen) in the solvent mixture of water and methanol.It crystallizes(C40H42MnN4O6,Mr=729.72) in monoclinic space group P21/c with a=1.362 77(17) nm,b=1.882 3(2) nm,c=1.252 53(16) nm;β=114.500(2)°,V=2.923 6(6) nm3,Dc=1.449 g·cm-3,Z=4,F(000)=1 320,R1=0.041 4,wR2=0.087 8.The crystal structure shows that the zinc atom is coordinated with three oxygen atoms from two p-acetamidobenzoic acids molecules and one water molecule respectively,two nitrogen atoms from the 1,10-phenanthroline,forming a distorted triangle bi-pyramid coordina-tion geometry.The result of TG analysis shows that the title complex was stable under 230.0 ℃.CCDC: 665257.
