 Title    ,1,1,1 -Tetrakis[triorganylphosphineaurio(I)]ethanium(+) Tetrafluoroborates - Hypercoordinated Species Containing [H3C -C (A u L )4I+ Cations  
 Abstract    Auriophilicity, Gold(I) Phosphine Complexes, Ethane-tetraaurio(I) Com pounds, X-Ray H ypercoordinate, tetraaurated carbon-complexes of the type [H3C -C (A u P R 3)4]+BF4~, R = Ph (1), R = C6H u (2), (PR3)2 = l,2-C 6H 4(C H 2C H 2P Ph2)2 (3) have been prepared by the reac­ tion o f the appropriate (phosphane)gold(I) chlorides with l,l,l-tris(dim ethoxyboryl)ethane H 3C -C [B (O M e)2]3 in the presence of CsF. The products have been characterized by standard analytical and spectroscopic methods, including single crystal X-ray analyses of 1 and 2. In each case the pentacoordinated carbon atoms have been located at the centre of a square pyr-amide built up by a methyl group at the apex and four gold atoms forming the base with short Au • • • Au distances of about 2.85 A, which strongly contribute to the form ation and stability of these species.

 Title    Electronic Structure Determination of Co(II)-Nucleotide Complexes by Using Magnetic and Mößbauer Emission Measurements  
 Abstract    M ößbauer Emission, M etal-Nucleotide Complexes, Electronic Structure M ößbauer emission spectroscopic and susceptibility measurements of several Co(II)-nu-cleotide complexes have been carried out. The electronic structure derived from these data for the Co(II) central cation has been related to the distortion and the symmetry of its environ­ ment. The susceptibility data are indicative of short antiferromagnetic ordering in the majority of the samples. For the hydrated Co-5'UM P (5'-uridine-monophosphate) and Co-5'CM P (5'-cytidine-monophosphate) complexes, magnetic models involving Co(II) dimers and linear chains, respectively, are proposed to explain the susceptibility data observed below 50 K.
