Here's a breakdown of the formula:

* Central Cage: The molecule forms a cage-like structure with four nitrogen atoms and six carbon atoms.

* Methylene Bridges: Each nitrogen atom is connected to two carbon atoms, forming "methylene bridges" (-CH2-).

* Symmetry: The molecule is highly symmetrical, with all four nitrogen atoms and six carbon atoms equivalent.

Important Note: This is a simplified representation of the structural formula. The actual molecule is three-dimensional, with the nitrogen atoms forming the corners of a tetrahedron.
