摘　　要：在不同条件下合成了［Ｃｏ（ｐｈｅｎ）ｍＸｐ］Ｙ１·ｎＨ２Ｏ型配合物，（ｍ＝１，２；ｐ＝１，２；１＝１－３；ｎ＝０－４；ｐｈｅｎ＝邻菲绕啉；Ｘ＝Ｃｌ－，Ｈ２Ｏ，酒石酸（ｔａｒｔ），甘氨酸（ｇｌｙ），α－皮可林酸（ｐｉｃ）．ＤＬ－两氨酸（ａｌａ），Ｌ－亮氨酸（ｌｅｕ），Ｌ－脯氨酸（ｐｒｏ）；Ｙ＝Ｃｌ－，］并进行了元素分析，热重分析，电子光谱，红外光谱和磁化率测定，计算它们的１０Ｄｑ和Ｂ值．Ｘ－ｒａｙ单晶衍射实验证明：［Ｃｏ（Ｐｈｅｎ）２（Ｈ２Ｏ）２］（ＮＯ３）３·２Ｈ２Ｏ，［Ｃｏ（Ｐｈｅｎ）２（ｇｌｙ）］Ｃｌ２·４Ｈ２Ｏ均为顺式结构．［Ｃｏ（Ｐｈｅｎ）（ａｌａ）２］Ｃｌ·３Ｈ２Ｏ，［Ｃｏ（Ｐｈｅｎ）（ｐｒｏ）２］ＣｌＯ４·４／３Ｈ２Ｏ均为ｔｒａｎｓ（Ｎ）结构．在［Ｃｏ（ｐｈｅｎ）２Ｘ２］（ｎ＋）型配合物中，Ｘ反位的键长均长于顺位键长，其反位效应的顺序为：Ｃｌ－＞羧基，ＮＨ２＞Ｈ２Ｏ。The mixed ligand coordination compounds, [Co(phen)mXp]Y1·nH2O (where m= 1, 2;P = 1, 2;1 = 1, 2, 3;phen = 1, 10- phenanthroline; X = Cl-, H2O, , tartate, α-picolinic acid,glycinc, DL-alanine, L-leuline, L-prolinc; Y= Cl-, NO3, ), were synthesized in different.condition. Their structures were studied by elemental analysis, thermogravimctric analysis,UV-Vis spectra. infrared spectra, susccptibility and X-ray single crystal cxperimental. Their 10Dq, Racah parameters B and electron clound expansion parameters β were calculated and their single crystal experiment show [Co(phen)2(H2O)2](NO3)3·2H2O, [Co(phen),(gly)]Cl2·4H2O, [Co(phen),(ala)2]Cl. 3H2O and [Co(phen)(pro)2]ClO4·4/ 3H2O are cis, cis, trans(N)and trans(N), respectively. The Co-N bond distances of trans to X atoms are slightly longerthan that of cis to X atoms in the [Co(phen)2X2](n+) complex.
