    How do we know if the transition metal complex with co-ordination number of 4 has tetrahedral or square planar structure?

    It depends.
    The only one that we need to that it is square planar is cis-platin as its named on the spec but I think that all others with 4 groups on are tetrahedral

    Square planar is rather unusual except for d8 complexes, and even then not all of them.

    Cis and transplatin are the only ones you need to know, though Rhodium, iridium and gold ions can form square planar complexes.

    As can most transition metals with enough electrons to form d8 ions...
