This thesis which includes three chapters discusses the syntheses and reactions of metal-metal quadruply bonded complexes containing hydrotris(1-pyrazolyl)borate ligand or polydentate phosphine. The first chapter discusses Re-Re bonded complexes containing tridentate phosphine ligand .The complexes Re2Cl5(η3-etp) (etp = Ph2PCH2CH2P(Ph)CH2CH2PPh2) and Re2Cl5(η3-tetraphos-2 ) (tetraphos-2 = P(CH2CH2PPh2)3) were prepared by reaction of Re2(OAc)2Cl4 with (CH3)3SiCl, followed by addition of etp and tetrhos-2 respcetively in THF. The etp and tetraphos-2 ligands coordinate to Re centers in tridentate fashions with chelating/bridging bonding modes. The lowest energy bands at 718nm and 753nm can be assigned to δ→δ* trasitions. Their electrochemical and spectrocopic properties have been recorded. The second chapter discusses the synthesis and structure of quadruply bonded complexes containing tridentate nitrogenous ligands. The complex Mo2(OAc)2(Tp)2 (Tp = HBPz3, Pz = pyrazolyl ) was prepared by reactions o[Mo2(OAc)2(CH3CN)6][BF4]2 with KTp in CH3CN. Crystal data for Mo2(OAc)2(Tp)2 : space group Cmc21, a = 13.769(3) A,b = 14.776(3) A,c = 16.074(3) A,V = 3270A3,Z = 4,which final residuals R = 0.0768,Rw = 0.773。The complex MoTp2 was prepared by reaction of [Mo2(CH3CN)8][BF4]4 with KTp in CH3CN. Crystal data for MoTp2 : space group P1,a = 12.256A,b = 12.273A,c = 30.031A,V = 4305A3,Z = 4. The thired chapter discusses reactions of quadruply bonded complexes containing tridentate nitrogenous ligands. Threaction of Mo2(OAc)4 with two equivalents KTP* ( Tp* = Hydridotris(3,5-dimethylpyrazoyl)borate ) in diglyme produces a red product that is proposed to be Mo2(OAc)2(Tp*)2 . This red product reacts with (CH3)3SiI in THF offered the organic salt [HB(Me2Pz)3BH][I] . Crystal data for [HB(Me2Pz)3BH][I] : space group Pmn21,a = 12.768A,b = 8.346A,c = 9.270A,V = 987.9A3,Z = 2,R = 0.0408,Rw = 0.0590。Reaction of the red product with HBr in THF yielded the complex [Me2PzH ][Br] . Crystal data for [Me2PzH][Br] space group C2/c,a = 7.0020A,b = 16.418A,c = 13.476A,V = 1545A3,Z = 6,R = 0.0499,Rw = 0.0704。
