Under hydrothermal conditions,2-(pyridin-4-yl)-1H-imidazole-4,5-dicarboxylaic acid(H_3PIDC)reacted with Gd(NO_3)_3 to give a 3D complex{[Gd(HPIDC)·(μ_4-C_2O_4)_(0.5)·H_2O]·2H_2O}_n(1).Single-crystal X-ray determination shows that complex 1 crystallizes in the monoclinic system,space group P2_1/c with a=8.287(8),b=14.796(14),c=11.559(11)A,β=90.969(15)°,Z=4,V=1417(2)A~3,C_(11)H_(11)GdN_3O_9,D_c=2.280 g/cm~3,M_r=486.48,λ(MoKa)=0.71073 A,μ=4.738 mm~(-1),F(000)=936,R=0.0248 and wR=0.0522.Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
Under hydrothermal conditions, 2- (pyridin-4-yl) -1H-imidazole-4,5-dicarboxylaic acid (H_3PIDC) reacted with Gd (NO_3) _3 to give a 3D complex {[Gd (HPIDC) · (μ_4-C_2O_4 ) _ (0.5) · H_2O] · 2H_2O} _n (1). Single-crystal X-ray determination shows that complex 1 crystallizes in the monoclinic system, space group P2_1 / c with a = 8.287 (8), b = 14.796 (11) GdN_3O_9, D_c = 2.280 g / cm ~ (14), c = 11.559 (11) A, β = 90.969 (15) °, Z = 3, M_r = 486.48, λ (MoKa) = 0.71073 A, μ = 4.738 mm -1, F (000) = 936, R = 0.0248 and wR = 0.0522. Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
