摘　　要：This paper reports a novel rare interesting crystal structures of gadolinium 2-fluorobenzoato (2-FBA) complex containing 1,10-phenanthroline (phen). The two non-equivalent binuclear molecules, [Gd(2-FBA)3(phen) (CH3CH2OH)]2 and [Gd(2-FBA)3(phen)]2, exist in the asymmetric unit of the crystal. The molecular structure of [Gd (2-FBA)3(phen)(CH3CH2OH)]2 shows that the Gd3+ ion is eight-coordinated by five O atoms from five 2-FBA groups and one O atom from one ethanol molecule and two N atoms from phen molecule. 2-FBA groups adopt monoden- tate and bridging two coordination modes. The molecular structure of [Gd(2-FBA)3(phen)]2 shows that the Gd3+ ion is coordinated by nine atoms, seven O atoms from five 2-FBA groups and two N atoms from phen molecule. The 2-FBA groups link Gd3+ ion in chelating, bridgingand chelating-bridgingthree coordination modes. CCDC: 273106.This paper reports a novel rare interesting crystal structures of gadolinium 2-fluorobenzoato （2-FBA） complex containing 1,10-phenanthroline （phen）.
