Kinetics Aspects of the Reversible Assembly of Copper in Heterometallic Mo3CuS4 Clusters with 4,4′-Di-tert-butyl-2,2′-bipyridine

“…The Mo–N bond distances in [Mo 3 (CuCl)­S 4 Cl 3 (dbbpy) 3 ] + are very close to those found in [Mo 3 S 4 Cl 3 (dbbpy) 3 ] + (2.237(8) Å), [Mo 3 (μ 3 -S)­(μ 2 -S 2 ) 3 (dtc) 2 (Me 2 phen)] 2+ (2.221(1), 2.210(1) Å), and [Mo 3 (μ 3 -Se)­(μ 2 -Se 2 ) 3 (phen) 3 ] 4+ (2.227(11), 2.237(11) Å) but shorter than in [Mo 3 S 4 Cl 3 (phen) 3 ] + (2.256(13) and 2.352(18) Å) and [Mo 3 S 4 (dtp) 2 (μ-AcO)­Cl­(Me 2 bpy)] (2.2700­(2) Å) . Moreover, despite the fact that no specific interactions between the [Mo 3 (CuCl)­S 4 Cl 3 (dbbpy) 3 ] + cation and the [CuCl 2 ] − anion are observed in the structure of [ 2 ]­[CuCl 2 ]·4CH 2 Cl 2 , the two Cu–Cl bond distances in the counterion are not identical, 2.042(5) and 2.036(5) Å, and slightly shorter than in other linear dichlorocuprates such as [Cu­(bipy) 2 ]­[CuCl 2 ] 2 (2.091(2) Å, 180°), [Cu­(tmeda) 2 ]­[CuCl 2 ] (2.095(4), 180°), [Cu­(1,10-phenanthroline) 2 ]­[CuCl 2 ] (2.0882(9), 2.0958(9), 178.75°), , and particularly that in the closely related cluster [Mo 3 CuS 4 {(R,R)-Me-BPE} 3 Cl 4 ]­[CuCl 2 ] ((+)-1,2-(R,R)-Me-BPE = bis­[(2 R ,5 R )-2,5-(dimethylphospholan-1-yl)]­ethane): 2.067(13) and 2.103(12) Å, 180°. The Cu–Cl distance within the cation cluster is also shorter: 2.146(2) versus 2.180(10) …”
