C. Daiguebonne et al., A NEW HONEYCOMB-LIKE MOLECULAR-COMPOUND - GD[C6H3(COO)(3)](H2O)(3)CENTER-DOT-1.5H(2)O, Journal of alloys and compounds, 277, 1998, pp. 50-53
The reaction in gel of Gd(III) ions with TMA(3-), where TMA(3-) stands
for [C6H3(COO)(3)](3-), has afforded single crystals of a bidimension
al molecular compound formulated as Gd[TMA(H2O)(3)]. 1.5H(2)O whose cr
ystal structure is reported here: C2/c, a = 20.454(2) Angstrom, b = 9.
973(1) Angstrom, c = 15.251(2) Angstrom, beta = 125.68(1)degrees and Z
= 8. The structure consists of parallel double-sheet networks based o
n honeycomb-like motifs based on Gd(III) ions and TMA(3-) groups. This
compound exhibits a paramagnetic behaviour in the whole temperature r
ange (2-300 K). (C) 1998 Elsevier Science S.A.
