The neutral metalloligand [CpFe(CO)2P(Se)(O(i)Pr)2] (Cp = η(5)-C5H5), which contains the rare secondary phosphite selenide moiety, reacts with different metal complex precursors to form six new heterobimetallic complexes containing M-Se-P-Fe(Cp) bond connectivity. The complexes [M(CO)5{CpFe(CO)2P(Se)(O(i)Pr)2}] (M = Cr, 1; M = W, 2), [MCl2{CpFe(CO)2P(Se)(O(i)Pr)2}2] (M = Pd, 3; M = Pt, 4), [Au4Cl4{CpFe(CO)2P(Se)(O(i)Pr)2}2], 5, and [AuI{CpFe(CO)2P(Se)(O(i)Pr)2}], 6, are all heterometallic, neutral, dinuclear (1, 2, 6), trinuclear (3, 4), and hexanuclear (5) complexes. The complexes were all prepared from straightforward substitution reactions (1-5) or as an adduct, 6. All new complexes were characterized by (1)H, (31)P, (77)Se NMR, infrared spectroscopy, elemental analysis and single crystal X-ray diffraction.
中性金属配合物 [CpFe(CO)2P(Se)(O(i)Pr)2]（Cp = η(5)-C5H5），其中含有罕见的次膦酸硒部分，与不同的金属配合物前体反应，形成六个新的含有 M-Se-P-Fe(Cp)键连接的杂双金属配合物。这些配合物为 [M(CO)5{CpFe(CO)2P(Se)(O(i)Pr)2}]（M = Cr，1；M = W，2）、[MCl2{CpFe(CO)2P(Se)(O(i)Pr)2}2]（M = Pd，3；M = Pt，4）、[Au4Cl4{CpFe(CO)2P(Se)(O(i)Pr)2}2]，5 和 [AuI{CpFe(CO)2P(Se)(O(i)Pr)2}]，6，均为异金属、中性、双核（1、2、6）、三核（3、4）和六核（5）配合物。这些配合物均通过简单的取代反应（1-5）或作为加合物 6 制备得到。所有新的配合物均通过 (1)H、(31)P、(77)Se NMR、红外光谱、元素分析和单晶 X 射线衍射进行了表征。
