metals Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Ag, and Au are present in 24 new water-soluble complexes containing the ligand tris(sodium-m-sulfonatophenyl) phosphane (TPPTS) which were synthesized from readily accessible precursor compounds and were isolated pure by gelpermeation chromatography. Some of these compounds are the first authentic examples of homoleptic TPPTS metal complexes, viz., Ni(TPPTS)3
金属锰,铁,钌,钴,铑,铱,镍,钯,铂,Ag和Au是存在于含有该配体的三(钠- 24新水溶性络合物米-sulfonatophenyl)膦(TPPTS),其分别为由容易获得的前体化合物合成,并通过凝胶渗透色谱法分离。这些化合物中的某些是均质TPPTS金属络合物的第一个可靠实例,例如Ni(TPPTS)3,Pd(TPPTS)3,Pt(TPPTS)4,Ag(TPPTS)2(TPPTS ★)和Au(TPPTS) )2(TPPTS ★)[TPPTS ★:P(C 6 H ^ 4 -米-SO 3 -的Na +)2(C 6 H ^ 4 -米-SO 3 -)],每个包含一个水每钠离子分子。值得注意的是,均质TPPTS配合物的配位数(TPPTS /金属比)低于母体三苯基膦(TPP)的相应配合物。
