Abstract: In this work, gadolinium nicotinate coordination compound with 1, 10-phenanthroline was synthesized and characterized as Gd(Phen)2L3 ·3H2O(where HL = nicotinic acid, Phen = 1,10-phenanthroline) by chemical analysis, IRspectrum, thermal analysis, crystal structure analysis. The crystal is triclinic with coordination number eight. The parameters of unit cell are a= 9. 031Å , 6= 12. 857Å, c=17. 747Å.a=84. 923°, β=80. 564°, γ=84. 706°. The bccteriostatic tests show that Gd(Phen)2L3· 3H2Ohas a stronger bacteriostasis than Phen and GdL3· 2H2O, especially to Candida albicans, hay bacillus and Pseudomonas aeruginosa.
