“…[30] These contacts are also similar to those of ligated homometallic Cu (nano)clusters,s uch as [Cu 25 (PPh 3 ) 12 H 22 ]Cl (av.2 .635 ) [31] or [Cu 29 Cl 4 H 22 (Ph 2 phen) 12 ]Cl (Ph 2 phen = 4,7-diphenyl-1,10-phenanthroline;av. [32] Theshortest d Cu-Cu found for 1 are the radial spacings between the central Cu atom and the inner Cu 12 shell (d CuA-CuB 2.434(2) ), along with those of the inner Cu B atoms and the outer Cu 30 Al 12 shell (d CuB-CuC 2.430(2)-2.436(3) ), as ituation which is in full agreement with the strain-induced compression discussed above.I nc ontrast, the tangential d Cu-Cu within the icosahedral shells are slightly elongated (d CuB-CuB /d CuC-CuC 2.555(2)-2.569(5) ).
