在有机胺的存在下,(Ph)_3SnCl与HOOCCH_2COOH反应,得到了一系列的五配位阴离子型有机锡化合物,分子结构通式为:Q[(Ph_3Sn)_3(O_2CCH_2CO_2)_2]·CH_3CH_2OH(Q=HNR_3=H_2NEt_2(1),HN(i-Pr)_2(2),N(n-Pr)_3(3),N(n-Bu)_3(4),HN((CH_2)_4CH_3)_2(5),并通过IR,~1H NMR,元素分析对这些化合物进行了表征.测定了[(i-Pr)_2NH_2][(Ph_3Sn)_3(O_2CCH_2CO_2)_2]·CH_3CH_2OH(2)的晶体结构.结果表明,化合物由3个锡原子的单体组成,锡原子为三角双锥结构,晶胞参数a=1.426 3(10)nm,b=1.999 6(13)nm,c=2.318 84(16)nm,β=90°,Z=8.
In the presence of organic amines, (Ph) _3SnCl reacted with HOOCCH_2COOH to give a series of pentacoordinated anionic organic tin compounds. The general molecular formula is: Q [(Ph_3Sn) _3 (O_2CCH_2CO_2) _2] · CH_3CH_2OH (Q = HNR_3 = H_2NEt_2 (1), HN (i-Pr) _2 (2), N (n-Pr) _3 (3), N (n-Bu) _3 (4), HN (CH_2) _4CH_3) _2 5), and the compounds were characterized by IR, ~ 1H NMR and elemental analysis.The crystal structure of [(i-Pr) _2NH_2] [(Ph_3Sn) _3 (O_2CCH_2CO_2) _2] · CH_3CH_2OH (2) The results show that the compound is composed of three tin atoms and the tin atom has a triangular double cone structure. The unit cell parameters a = 1.426 3 (10) nm, b = 1.999 6 (13) nm and c = 2.318 84 , β = 90 °, Z = 8.
