چکیده
A mononuclear complex (CO)sReL,Cl (la) (L = NHsCHMe,) and a dinuclear CO, complex (CO)sL,Re(~,nl,ql-COs)Re(CO)qL (2) are prepared from the reaction of a carbamoyl complex, (CO),ReUCONHCHMe,) with H,O in CHCl,. The coupling of a proposed intermediate (CO),LReCOOH with la is a viable process for the formation of complex 2. The structures of (CO),ReL,Cl (lb) (L =NH,CH,CH=CH,) and 2 have been established by X-ray diffraction.

Synthesis and structures of doubly-bridged dicyclopentadienyl dinuclear rhenium complexes, and their photochemical reactions with aromatic halides in benzene.
Reaction of the doubly-bridged biscyclopentadienes (C5H4(EMe2))(C5H4(SiMe2)) (E = Si(1a), or C(1b)) with Re2(CO)10 in refluxing mesitylene gave the corresponding dirhenium carbonyl complexes [(η(5)-C5H3)2(EMe2)(SiMe2)][Re(CO)3]2 (trans-2a,b and cis-2a,b), and the desilylated products [(η(5)-C5H4)2(EMe2)][Re(CO)3]2 (3a,b). Photolysis of trans-2a,b with a series of aryl halides in benzene results...

A new two-dimensional manganese(II) coordination polymer, [Mn(μ-DEP)(μ-Cl)(H2O)2]n (1) (DEP is diethyl phosphate), was prepared from the reaction of MnCl2.4H2O and TEP (TEP is triethyl phosphate) ligand in mixture of H2O/CH3OH (1:10) at 40 °C. Suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced colorless solution at room temper...

Twelve novel Re(I) acetonitrile complexes of the type [Re(CO)3(L)(MeCN)][WCA], with L being a chelating bis(NHC) ligand with alkylene-bridged and N-substituted bis(imidazolineylidene) moieties, and WCA (WCA = weakly coordinating anion) representing PF6(-) and [Al(OC(CF3)3)4](-), have been synthesized. 1D and 2D NMR spectroscopy as well as IR spectroscopy, elemental analysis and X-ray crystallog...
متن کاملTernary self-assemblies in water: forming a pentanuclear ReLn4 assembly by association of binuclear lanthanide binding pockets with fac-Re(CO)3(dinicotinate)2Cl.
The self-assembly of higher order structures in water is realised by using the association of 1,3-biscarboxylates to binuclear meta-xylyl bridged DO3A complexes. Two dinicotinate binding sites are placed at a right-angle in a rhenium complex, which is shown to form a 1 : 2 complex with α,α'-bis(Eu·DO3A)-5-amino-m-xylene.
