Figure 3
Two complementary packing views of the structure drawn (a) along c, with the aqua–La–crotonate chains running vertically, and (in projection) the adenine–water planes connecting them, and (b) along a, with the aqua–La–crotonate chains (now in projection, coming out of the figure) interconnected through hydrogen bonding by the (slanted) adenine–water planes. The crotonate ligands have been represented only by their carboxylate ends for clarity. Dashed lines indicate hydrogen bonds. [Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x + 1, −y + 1, −z + 1; (iii) −x + 1, −y, −z + 1; (iv) −x + 1, −y, −z.] |
