The perovskite structure is a type of crystal structure common to many materials with the general formula \(ABX_3\). In this structure:

- \(A\) cation is larger and typically occupies the corners of the cubic unit cell.
- \(B\) cation is smaller and sits at the center of the unit cell.
- \(X\) anion is positioned at the face centers of the cube, forming octahedra around the \(B\) cation.

Here is a simple representation of a perovskite crystal structure:

```
           X   X   X
            \ / \
       A-- X--B--X--A
            / \ / \
           X   X   X
```

In the 3D structure, the \(A\) cations are at the corners of the cube, the \(B\) cation is in the center, and the \(X\) anions are in the middle of each face of the cube.
