1,2-Ethylenediphosphonic acid reacts with gallium nitrate in water to give new pillared layered galliumphosphonates, the structure of which depends on the experimental conditions used for their preparation. Thus,Ga4(O3PC2H4PO3)3 (1) and Ga2(OH)2(O3PC2H4PO3) (2) were isolated and the structure of 1 was solved by single-crystal X-ray diffraction, while 2 was shown to have the same metal/PO3 arrangement as the previously describedGa(OH)(O3PCH3). Ga4(O3PC2H4PO3)3 (1) is triclinic, with space group P
with Z = 2, a = 5.1480(4), b =8.0354(7), and c = 12.383(1) Å; 
= 91.34(1), 
= 101.40(1), and 
= 90.86(1)
; V = 501.9(1) Å3. The structureof 1 is unusual with (i) mixed GaO4 and GaO5 sites while a 6-fold coordination is observed for gallium in (2) and(ii) the presence of the organic moiety within both the layers and the interlayer space. The two compounds werefully characterized using 31P and 71Ga solid-state NMR.
