  摘要：

  N, N-Diethylammonium diselenophosphinate, [Et2NH2][Se2PR2] (R = CH2CH2Ph), under mild conditions (r. t., CH2Cl2) reacts with ZnBr2 to afford discrete tetranuclear cluster [Zn-4(mu(4)-Se){Se2PR2}(6)] in 63% yield, which consists of Se-centered distorted Zn-4 tetrahedron ligated by six edge-bridged diselenophosphinato anions (mu(2), mu(2)). In the presence of Na2S2O3 as a S2- source, this reaction provides structurally similar S-centered cluster, [Zn-4(mu(4)-S){Se2PR2}(6)], in 76% yield. Finally, at the interaction of the N, N-diethylammonium diselenophosphinate with ZnBr2 and pyridine N-oxide (the reagent ratio is stoichiometric), the zigzag polymer {ZnBr(mu-Se2PR2)[PyNO]}(n), bearing a "SeZnSeP" repeating chain, was formed in 84% yield.
