Table 2. Cation exchange ^a (%) for [(Fp–L)_x(TEA)_3–x][In₃(BTC)₄] under various conditions determined by ICP-OES ^b (x = 3 corresponds to 100%).

[TEA]3[In3(BTC)4] + x[Fp–L][BF4] → [(Fp–L)x(TEA)3–x][In3(BTC)4] + x[TEA][BF4]
24 h (soaking, 25 °C)	24 h (soaking, 5 °C)	48 h (soaking, 5 °C)
23% (x = 0.69)	15% (x = 0.45)	20% (x = 0.60)

^aConditions: 0.02 M solution of [Fp–THF][BF₄] in dry acetone, initial ratio [(Fp–L)⁺]/[TEA] = 1/1.

^bDigestion in diluted HNO₃ (1/10 v/v).
