Bis(1,10-phenanthroline-N,N′)(thiosulfato-O,S)nickel(II)–water–methanol (1/0.92/1.4) and bis(2,2′-bipyridyl-N,N′)(thiosulfato-O,S)nickel(II)–water–methanol (1/2/0.55)

Abstract

The title compounds, [Ni(S(2)O(3))(C(12)H(8)N(2))(2)].0.92H(2)O.1. 4CH(4)O and [Ni(S(2)O(3))(C(10)H(8)N(2))(2)].2H(2)O.0.55CH(4)O, are monomeric, containing nickel(II) in a distorted octahedral coordination environment provided by the four N atoms of two bidentate bipy or phen groups and one S and one O atom from a chelating thiosulfate anion. The crystals are highly unstable outside their mother liquors and are stabilized in solution by a not fully determined number of water and methanol solvate molecules. The phenanthroline structure includes two independent moieties related by a non-crystallographic inversion center. The thiosulfate anions display the usual S-O lengthening found when the anion acts in a bidentate mode.

“…The Ni–O distances of chelating S 2 O 3 2– in complex 1 do not change significantly [2.069(6)–2.091(6) Å] and are slightly shorter than those found in other Ni II thiosulfate complexes [2.093(3)–2.110(3) Å16c and 2.142(2) Å16d (Table 3). Also Ni–S and Ni–N distances, which are in the range of 2.434(2)–2.562(3) Å and 2.063(7)–2.091(8) Å, respectively, are close to the mean values found in other octahedral Ni II thiosulfates that contain N‐ligands 15b,16c,16d.…”
