Crystal structure of bis{2-[bis(2-hydroxyethyl)amino]ethanol-κ3 O,N,O′}zinc terephthalate
نویسندگان
چکیده
In the title salt, [Zn(C6H15NO3)2](C8H4O4), the Zn(II) cation, located on a centre of inversion, is coordinated by four O atoms and two N atoms from two tridentate 2-[bis-(2-hy-droxy-eth-yl)amino]-ethanol (BHEA) ligands, giving rise to a slightly distorted octa-hedral geometry. The terephthalate dianion, located about a centre of inversion, is not coordinated to Zn(II) but is connected through O-H⋯O contacts with [Zn(BHEA)2](2+) cations, leading to a three-dimensional crystal structure.
