AH. that's a little clearer. we'll use Fdim as our example chord.
Fdim (in root position) to a C/E (first inversion) is a nice sound. Note that Fdim isn't really in the key of C, although it is in F# (lol at completely opposite keys). alternatively, going to a C sus4 chord with the sus in the bass, resolving downward, is a nice sound. you can substitute either of these chords with an F# chord to make it a true vii-I cadence, they both have distinctive and enjoyable sounds.
if you're looking for something within the key and made specifically for it, your typical vii6-I is fine.
going from our Fdim in first inversion (Fdim/Ab) to a I64-V7 figure in C (C/G, G7) to the true root, F#, is a slightly more involved way to fool with the key and your ears. harder to pull off, due to inversions and the like.
need more?
edit - another nice one is going from our Fdim/Ab to A major, A minor, I64-V7-I in D major, or Eb/G works well too.
