摘要

The reaction in gel of Gd(III) ions with TMA³⁻, where TMA³⁻ stands for [C₆H₃(COO)₃]³⁻, has afforded single crystals of a bidimensional molecular compound formulated as Gd[TMA(H₂O)₃]·1.5H₂O whose crystal structure is reported here: C2/c, a=20.454(2) Å, b=9.973(1) Å, c=15.251(2) Å, β=125.68(1)° and Z=8. The structure consists of parallel double-sheet networks based on honeycomb-like motifs based on Gd(III) ions and TMA³⁻ groups. This compound exhibits a paramagnetic behaviour in the whole temperature range (2–300K).
