Poorly soluble zinc ethylenediaminetetraacetate zincate Zn[ZnL] reacts with sodium Na4L, potassium K4L, ammonium (NH4)4L, 2-ammonioethanol (H3NCH2CH2OH)4L, and hexamethylene-1,6-diammonium {H3N(CH2)6NH3}2L salts of ethylenediaminetetraacetic acid H4L to give readily soluble sodium Na2[ZnL], potassium K2[ZnL], ammonium (NH4)2[ZnL], 2-ammonioethanol (H3NCH2CH2OH)2[ZnL], and hexamethylene-1,6-diammonium {H3N(CH2)6NH3}[ZnL] ethylenediaminetetraacetate zincates. The reaction of tetrakis(triethylammonium) salt {(C2H5)3NH}4L with Zn[ZnL] does not give the expected bis(triethylammonium) ethylenediaminetetraacetate zincate {(C2H5)3NH}2[ZnL], but gives instead mono(triethylammonium) ethylenediaminetetraacetate zincate, {(C2H5)3NH}H[ZnL]; in aqueous solution, this product generates poorly soluble zinc ethylenediaminetetraacetate H2[ZnL(H2O)]·2H2O, which was studied by X-ray diffraction (CCDC no. 2172274).
