Abstract—The gadolinium nitrato complex with -furancarboxylic acid (FA) and 2,2'-dipyridyl (Dipy) has
been synthesized. According to X-ray diffraction results, the complex is composed of the
[Gd(FA)₂(NO₃)(Dipy)]₂ dimers. The crystals are triclinic: a = 9.942(2) Å, b = 10.231(2) Å, c = 11.037(2) Å,
= 85.50(3), = 75.71(3), = 69.82(3), Z = 1. Two gadolinium atoms are linked by four carboxylate groups
of furancarboxylic acid molecules. Each gadolinium atom is coordinated to seven oxygen atoms (five belonging
to the FA carboxyl groups and two belonging to the bidentate nitrate group) and to two nitrogen atoms (from
Dipy).
