Synthesis and Application of Tunable Mo2 and W2 Tetraguanidinate Paddlewheel Complexes
… Experiments show the electron deficient vacant dimetal axial site and the electron rich guanidinate core work together similar to frustrated pairs. Acetic acid protonates the guanidinate while simultaneously coordinating to the metal center. This newly discovered synergistic bonding decreases …

Analysis of dirhenium carboxylate : purine dinucleotide adducts
… complexes as chemotherapeutic agents. Anticancer dimetal complexes such as Re<sub>2</sub>(O<sub>2</sub>CCH<sub>2</sub>CH<sub>3</sub>)<sub>2</sub>Br<sub>4</sub>·2H<sub>2</sub>O are proposed to prevent replication of cancel cells by coordinating to the purine nucleobases in DNA. To investigate the …

Synthetic investigation of Mn(I) and Re(I) N-heterocyclic carbene complexes
… by nBuLi as base and [Mn2(CO)10] as dimetal substrate lead to the isolation of the target dinuclear complex [Mn2(CO)9IMes] (9). Other novel complexes obtained during the course of this study include the biscarbene tetrarhenium complex [Re2(CO)9.C(OEt)C4H2OC(OEt)Re2(CO)9] (12) and …

Biochemical Characterization of Self-Sacrificing P-Aminobenzoate Synthases from Chlamydia Trachomatis and Nitrosomonas Europaea
… synthase activity is reliant on an oxygenated dimetal cofactor and despite the crystal structure of CADD depicting a diiron active site, we have demonstrated that CADD's pABA synthase activity is dependent on a heterodinuclear Mn/Fe cofactor. Conversely, NE1434 demonstrates no preference for …

Applications Of Electronic Structure Theory To Problems In Unimolecular Dissociation And Inorganic And Biochemical Systems
… to be more stable than a Cs isomer in which the dimetal unit is perpendicular to the C8 ring axis. Similar coaxial structures are predicted for Pa2(C8H8)2 and Np2(C8H8)2, while in Th2(C8H8)2 the C8H8 rings tilt away from the An-An axis. Further thermodynamic calculations suggest that it may be …
