    4, respectively, where L' is the monoionized iminoacetamide ligand R'N=C(H)-C(=O)-NR'(-). Finally, the reaction of Re(V)O(OEt)X(2)(PPh(3))(2) with L has furnished bivalent species of type Re(II)X(2)(L)(2), 6(X = Cl, Br). The X-ray structures of 1 (R = Me, R' = Ph), 3 (R = H, R' = Ph, Ar = Ph), and 4 (R = H, R' = cycloheptyl, Ar = C(6)H(4)Cl) are reported revealing meridional geometry for the ReCl(3)

The chemical compositions of all the complexes were established by spectroscopic methods and the molecular structures of 1a, 2b, 3a, 3b, 5 and 6 were determined by single-crystal X-ray diffraction. It was proved that some of the complexes 1–6 and their previously obtained congeners are very

    A novel PNN-type pincer ligand has been accessed via imine reduction with LiAlH4 to provide the phosphine diamino proligand, PNHNH (1). The ligand, 1, as well as PNHP can be metallated directly, via N–H cleavage, with L2ReOX2(OEt) precursors to access six-coordinate (PNP)ReOCl2 (2) and (PNNH)ReOX2 (3-Cl, X = Cl; 3-Br, X = Br) in good yield. 3-Cl and 3-Br undergo dehydrohalogenation upon treatment with

    Syntheses of Re and Mn carbonyl complexes of the diarylamido/bis(phosphine) PNP pincer ligand are reported. The saturated (PNP)Re(CO)3 and (PNP)Mn(CO)3 react cleanly with HBr in acetic acid to undergo decarbonylation with concomitant addition of HBr across the N-M bond. The resultant (PNHP)MBr(CO)2 (M = Mn or Re) complexes can be dehydrobrominated with triethylamine to yield the unsaturated (PNP)M(CO)2

    XX–NhNh–NaNa donor sites (Nh, heterocyclic nitrogen; Na, azo nitrogen) is uniformly cis–trans–cis. In the structure of [Re(L)3]ReO4 the tris chelate has facial geometry. The isomer preference of both families is exclusive, no other isomer having been observed in any of the preparations. The 1H NMR spectra of the tris chelates are consistent with the facial geometry. The bis chelates are one-electron paramagnets
