are
a

Abstract
Homochiral
triangular
prisms,
cuboid
cages,
and
capped
polyhedral
cages
are
successfully
synthesized
via
coordination‐driven
self‐assembly.
Typical
tartrate
ligands
demonstrated
notable
torsional
flexibility
variable
coordination
numbers,
allowing
for
diverse
patterns,
including
saturated
chelation
terminal
mono‐coordination
with
half‐sandwich
rhodium
iridium
fragments.
The
ligand
lengths,
molar
ratios,
metal
vertices
meticulously
designed
fine‐tuned
to
yield
chiral
entirely
distinct
architectures.
Tartrate
exhibits
abundant
hydrogen
bonding
interactions
induction
capabilities,
these
supramolecular
assemblies
characterized
by
single‐crystal
X‐ray
diffraction,
nuclear
magnetic
resonance,
circular
dichroism
spectroscopy.
An
efficient
method
is
developed
constructing
structurally
versatile
cage‐like
entities,
facilitating
self‐assembly
in
complicated
multi‐component
systems.
