Zn_{4}Ln_{11} [with Ln = Gd(**1**) or Dy(**2**)] coordination clusters, best formulated as {Zn_{2}Ln_{2}}[Ln_{9}]{Zn_{2}}, are presented. The
central {Ln_{9}} diabolo core has a {Zn_{2}Ln_{2}} handle motif pulling at two outer Ln ions of the central
core via two {ZnLn} units, which also invest the system with *C*_{2} point symmetry. The resulting cluster motif
is supported on two Zn “feet”, corresponding to the
{Zn_{2}} unit in the formula. A thorough investigation of
the magnetic properties in the light of the properties of previously
reported {Ln_{9}} diabolo compounds was undertaken. Up to
now, the spin structure of such diabolo motifs usually proves ambiguous.
Our magnetic studies show that the orientation of the central spin
in the {Gd_{9}} diabolo plays a decisive role. In stabilizing
the core by attachment of the {Zn}^{2+} “feet”
and using the *C*_{2} symmetry related {ZnGd}^{5+} handles to influence the spin direction of the central Gd
of the {Gd_{9}} diabolo, we can understand why the “naked”
{Gd_{9}} diabolo shows ambiguous spin structure. This then
allowed us to elucidate the single-molecule magnetic (SMM) properties
of the Dy-based compound **2** through disentangling the
magnetic properties of the isostructural Gd-based compound **1**.
