Reactions between ethylenediamine (en) solutions of the intermetallic Zintl phases K(3)E(7) (E = P, As) and a series of homoleptic post-transition metal organometallics such as Cu(5)(Mes)(5), M(C(6)H(5))(2) (M = Zn, Cd) and In(C(6)H(5))(3) have yielded a family of novel bimetallic cluster anions. These new species were isolated as K(2, 2,2-crypt) salts in K(2,2,2-crypt)Cu(2)E(14) (E = P (1), As (2)), K(2,2,2-crypt)ZnE(14) (E = P (3), As (4)), K(2,2,2-crypt)CdP(14) x 6py (5) and K(2,2,2-crypt)E(7)InPh(2) (E = P (6), As (7)). Species 2, 3, 5 and 6 were crystallographically characterised by single-crystal X-ray diffraction. The stability of all of the cluster anions in solution was confirmed by electrospray mass-spectrometry and by (1)H, (13)C{(1)H} and (31)P{(1)H} NMR spectroscopy when possible.
乙二胺溶液与 Zintl 相 K(3)E(7)(E = P、As)和一系列同核后过渡金属有机金属化合物如 Cu(5)(Mes)(5)、M(C(6)H(5))(2)(M = Zn、Cd)和 In(C(6)H(5))(3)之间的反应生成了一系列新型双金属簇阴离子。这些新物种作为K(2,2,2-crypt)盐被分离出来，在K(2,2,2- crypt)Cu(2)E(14)(E = P(1)、As(2))、K(2,2,2- crypt)ZnE(14)(E = P(3)、As(4))、K(2,2,2- crypt)CdP(14)x6py(5)和K(2,2,2- crypt)E(7)InPh(2)(E = P(6)、As(7))中。通过单晶 X 射线衍射对 2、3、5 和 6 种物质进行了晶体学表征。通过电喷雾质谱和在可能的情况下通过(1)H、(13)C{(1)H}和(31)P{(1)H}NMR 光谱，确认了所有簇阴离子在溶液中的稳定性。
