Try using Spacings.

Grid[{{Grid[{{a, b}, {c, d}}, Dividers -> Center,
     Background -> Orange], e}, {f, g}}, Frame -> All,
  Spacings -> {0, 0}]

And of course the inner and outer Grids can have different Spacings.

Grid[{{Grid[{{a, b}, {c, d}}, Background -> Orange,
     Dividers -> Center, Spacings -> {3, 3}], e}, {f, g}},
  Frame -> All, Spacings -> {0, 0}]



Grid[{{Grid[{{a, b}, {c, d}}, Background -> Orange,
     Dividers -> Center, Spacings -> {3, 3}], e}, {f, g}},
  Frame -> All, Spacings -> {{0, {0}, 10}, {0, {0}, 20}}]


I get a very slight defect on some of these, with the orange background 
not *quite* filling down to the Frame between {c,d} and f.
