I think lots of UK/US pairs will satisfy this, e.g. FHI and MIRI. (I think I (in the UK) can make tax-deductible donations to FHI, but not MIRI; and I think Americans have it the other way around.)
Americans can make tax-dedutible donations to FHI through Americans for Oxford: http://www.fhi.ox.ac.uk/support-fhi/
CEA then; it’s currently only tax-deductible if you give via an intermediary that takes 5%.
I’m pretty sure I know of a case where this is done with these exact charities.
