Metal building blocks with four functional groups are
required for this topology.
Ligand building blocks with two functional groups are required for
this topology.
When using a :class:`dict` for the `building_blocks` parameter,
as in :ref:`cage-topology-graph-examples`:
*Multi-Building Block Cage Construction*, a
:class:`.BuildingBlock`, with the following number of functional
groups, needs to be assigned to each of the following vertex ids:
| 4-functional groups: 0 to 5
| 2-functional groups: 6 to 17
See :class:`.Cage` for more details and examples.
