The crystal structures of ClO4 (1) and ClO4 (2) have been determined by single-crystal X-ray diffraction methods at 295 K, being refined by least-squares methods to residuals of 0.10 and 0.08 for 591 and 1294 independent 'observed' reflections respectively.The two compounds are isomorphous (rhombohedral, space group R3, and Z=2) with a=19.02(2) Angstroem, α=44.06(6) deg and a=19.085(5) Angstroem, α=43.90(1) deg respectively; the cation lies on a site of 3 symmetry, while the anion is disordered about a site of 3 symmetry.The metal-atom geometry is pseudo-tetrahedral .For the structure determination of ClO4 (3) obtained by the recrystallization of ClO4 from pyridine (py), 2843 'observed' reflections were refined to a residual of 0.052.Crystals are triclinic, space group P1/, with a=15.599(4), b=13.413(4), c=10.982(4) Angstroem, α=79.51(3), β=70.47(3), γ=86.03(3) deg, and Z=2.Cu-P=2.271(4), 2.295(3) Angstroem and Cu-N=2.102(7), 2.115(8) Angstroem in a pseudo-tetrahedral copper(I) environment, with P-Cu-P=115.85(9) deg and N-Cu-N=101.5(2) deg.The 2,2'-bipyridyl (bipy) analogue ClO4 (4) is monoclinic, space-group P21/c, with a=10.210(3), b=15.085(4), c=28.455(9) Angstroem, β=109.13(2) deg, and Z=4.Cu-P=2.246(3), 2.256(3) Angstroem and Cu-N=2.056(8), 2.113(9) Angstroem, with P-Cu-P=125.4(1) and N-Cu-N=79.6(4) deg.R was 0.081 for 2605 reflections. , by contrast, yields a hemipyridine solvate, (5), on recrystallization from pyridine; crystals are triclinic, space group P1/, with a=12.849(6), b=10.319(5), c=13.618(6) Angstroem, α=102.91(4), β=101.91(4), γ=73.42(4) deg, and Z=2.The structure was refined to a residual of 0.051 for 3633 independent 'observed' reflections, and is isomorphous with the hemibenzene solvates of (X=Cl or Br) and .
