What is the name for an object that could be simplified into two separate objects?

If I have a model of some sort which looks like this.

object 1 -
    property A - value A
        property X - value X
        property Z - value Z
    property B - value B
        property X - value X
        property Z - value Z

How would I refer to these types of structures in an OOP language? I frequently run into this type of structure in various OOP languages. I would like to reference this type of structure and say:

'reduct the ____ structures into simplest states.'
