Abstract: 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. 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. |
