- W1999722443 abstract "Two novel polymeric carboxylato-bridged gadolinium(III) complexes of formulae, [Gd 2 (fum) 3 (H 2 O) 4 ] · 2H 2 O ( 1 ) and [Gd 2 (tart) 3 (H 2 O) 2 ] · 3H 2 O ( 2 ) (fum, fumarate dianion; tart, tartrate dianion) have been synthesized and characterized by single crystal X-ray diffraction studies, low-temperature magnetic measurements and thermal studies. Two novel polymeric carboxylato-bridged gadolinium(III) complexes of formulae, [Gd 2 (fum) 3 (H 2 O) 4 ] · 2H 2 O ( 1 ) and [Gd 2 (tart) 3 (H 2 O) 2 ] · 3H 2 O ( 2 ) (fum, fumarate dianion; tart, tartrate dianion) have been synthesized and characterized by single crystal X-ray diffraction studies, low-temperature magnetic measurements and thermal studies. The structure determination reveals a 3D network containing nine coordinated Gd(III) ions: for complex 1 , the coordination sphere of gadolinium(III) comprises of two water molecules and seven oxygen atoms from fumarate dianions and for complex 2 , a water molecule and eight oxygen donors from tartrate dianions. Variable-temperature magnetic susceptibility measurement reveals the existence of a weak antiferromagnetic coupling through the gadolinium ions. The best-fit parameters for complex 1 , assuming a simplified structural model led to J = −0.0076 cm −1 , g = 2.0, R = 2 × 10 −5 whereas for complex 2 the double-layered structure inside the 3D network impedes the possibility to calculate the J value(s)." @default.
