As shown in Figure S1, In the asymmetrical units of 1, there are three
crystallographically independent Eu3+ ions and two SO42- anions.

All the Eu3+ cations are nine-coordinated in a tricapped trigonal prism. In addition
to one interstitial and four hydroxide O atoms, The Eu1 ions are coordinated by two
OS atoms from two distinct SO42- anions and two water molecules; the Eu2 ions are
bonded to three OS atoms of three SO42- anions and one water molecules; and the
remaining coordination positions of Eu3 atoms are occupied by the four OS atoms of
three SO42- anions. The Eu-O bond distances are in the range of 2.34 to 2.68 Å.
Figure S5. Two types of coordination modes of SO42- anions in 1.
The two unique SO42- anions adopt two different coordinations: one behaves as a
μ5-SO4 mode linking four Eu atoms in one bidentate and three monodentate modes;
the other acts as μ4-SO4 mode connecting four Eu centers in four monodentate modes.

Figure S8. 1-D ladderlike chain running along the b axis.
The hexanuclear [Eu6(μ6-O)(μ3-OH)8]8+ cluster units are connected through
bridging μ2-OS to form an interesting 1-D zigzag inorganic lanthanide cluster chain
running along the a axis, furthermore, there are two types of ladderlike chains built
from hexanuclear [Eu6(μ6-O)(μ3-OH)8]8+ cluster units bridged by SO42- anions running
along the b and c axis.
