I'm not trying to be pedantic here. I'm just not familiar with any historical event you are describing.
From what I've heard, and I'm not an expert, I wouldn't characterize any of the conquests of Babylon as a 'razing', And the eventual abandonment of the city was more a result of slow decline and changing geological conditions.
I do like to learn about the history of the area, so if it's just something I'm not familiar with, please point me in the right direction.
