N,N,N,N′,N′,N′-Hexa­kis­(2-hy­droxy­ethyl)butane-1,4-diaminium bis­(2-sul­fan­ylidene-1,3-di­thiole-4,5-dithiolato-κ²S⁴,S⁵)zincate

In the asymmetric unit of the title compound, (C₁₆H₃₈N₂O₆)[Zn(C₃S₅)₂], two independent cations lie across inversion centers. In one of the cations, the three symmetry-unique O—H groups are disordered over two sets of sites with refined occupancy ratios of 0.701 (9):0.299 (9), 0.671 (8):0.329 (8) and 0.566 (7):0.434 (7). In the anion, the Zn^II ion is coordinated in a distorted tetra­hedral environment by four S atoms of two chelating 1,3-di­thiole-2-thione-4,5-dithiolato ligands. The dihedral angle between the mean planes [maximun deviations = 0.022 (3) and 0.0656 (6) Å] of the two ligands is 87.76 (3)°. An intamolecular O—H...O hydrogen bond occurs in the disordered cation. In the crystal, O—H...O and O—H...S hydrogen bonds link the components into a two-dimensional network parallel to (0-11).

Bis(μ-6-meth­oxy-2-{[(3-oxidoprop­yl)imino]­meth­yl}phenolato)nickel(II) methanol monosolvate

The mol­ecular structure of the title complex, [Ni₂(C₁₁H₁₃NO₃)₂]·CH₃OH, contains two Ni^II atoms and two doubly deprotonated 6-meth­oxy-2-{[(3-oxidoprop­yl)imino]­meth­yl}phenolate ligands. The Ni^II atoms are each four-coordinated in a distorted square-planar geometry by three O atoms and one N atom derived from the phenolate ligands. The solvent mol­ecule is linked to the complex mol­ecule by two O—H...O hydrogen bonds.
