Two novel nickel thiosulfate complexes have been prepared and their crystal structures determined: NiS2O3(dmph)(H2O)·H2O·CH3OH (1) (dmph = 2,9-dimethyl-1,10-phenanthroline), which to our knowledge is the first pentacoordinated nickel thiosulfate complex described so far, and NiS2O3(dmph) (2), a hexacoordinated complex which displays a thiosulfate binding mode with no precedents in the literature, viz. bridging solely through oxygen. Compound (1) is monoclinic, C2/c, a 26.269(5), b 7.641(3), c 18.381(3) Å, β 97.00(2)°, V 3662(2) Å 3,Z 8, conventional R (on F) being 0.049 for 2217 No observed reflections (I > 2σ(I)). Compound (2) is also monoclinic, P21/n, a 11.108(2), b 10.955(2), c 11.666(2) Å, β 103.32(3)°, V 1381.4(5) Å3, Z 4, R 0.036, No 2497.
