A new structure type
of composition Ce<sub>6</sub>Co<sub>5</sub>Ge<sub>16</sub> was grown
out of a molten Sn flux. Ce<sub>6</sub>Co<sub>5</sub>Ge<sub>16</sub> crystallizes in the orthorhombic space group <i>Cmcm</i>, with highly anisotropic lattice parameters of <i>a</i> = 4.3293(5) Å, <i>b</i> = 55.438(8) Å, and <i>c</i> = 4.3104(4) Å. The resulting single crystals were
characterized by X-ray diffraction, and the magnetic and transport
properties are presented. The Sn-stabilized structure of Ce<sub>6</sub>Co<sub>5</sub>Ge<sub>16</sub> is based on the stacking of disordered
Ce cuboctahedra and is an intergrowth of existing structure types
including AlB<sub>2</sub>, BaNiSn<sub>3</sub>, and AuCu<sub>3</sub>. The stacking of structural subunits has previously been shown to
be significant in the fields of superconductivity, quantum materials,
and optical materials. Herein, we present the synthesis, characterization,
and complex magnetic behavior of Ce<sub>6</sub>Co<sub>5</sub>Ge<sub>16</sub> at low temperature, including three distinct magnetic transitions.
