What's an example of a t-shaped molecules and how does this shape come to be? What stops the atoms attached to the central atom from getting as far away from each other as possible and forming a trigonal planar shape?

Lone pairs prefer the equatorial position because if you put them equatorial you have only 2 lone pair bonding pair angles whereas if you put them axial you have 6 lone pair bonding pair angles. You always want to minimize the number of lone pair bonding pair angles.

An example of a T-shaped molecule would be BF3 or ClF3.
