The title compound, [Ni(CHS)], , is a square-planar -symmetric compound that occurs on a general position in non-centrosymmetric tetra-gonal 422 (No. 92) with ¼ eq of -pentane (CH) as co-crystallite. Intra-ligand bond lengths show the di-thiol-ene ligands to be in their half-oxidized radical monoanionic form. Inter-molecular Bu-C-H⋯arene and Bu-C-H⋯NiSC close contacts guide the packing arrangement for .

The title compound, [Ni(C(5)HF(6)O(2))(2)(C(12)H(9)BrN(2))], the Ni(II) atom exhibits a pseudo-octa-hedral coordination geometry. The structure packs through C-H⋯Br inter-actions, forming a hydrogen-bonded ladder. There are also strong hydrogen-bonding inter-actions between two of the O atoms of the β-diketonate ligands and two H atoms on the pyridine ring of the Schiff base ligand.

In the title compound, [Ni(C(5)H(7)O(2))(2)(C(12)H(16)N(3)O(2))], the Ni(II) cation is hexa-coordinated by four O and two N atoms, showing a slightly distorted octa-hedral geometry. The Ni(II) cation lies on an inversion centre, as a consequence of which the asymmetric unit comprises one half-mol-ecule. The four O atoms belonging to two pentane-2,4-dionate ligands lie in the equatorial plane and two pyridyl N atoms occupy the axial coordination sites.

The potentially pentadentate ligand 2,6-bis[N-(2'-pyridylmethyl)carbamyl]pyridine (H2L1), readily prepared from reaction of a diester of pyridine-2,6-dicarboxylic acid (H2dipic) and 2-aminomethylpyridine (ampy), shows limited tendency to form 1:1 M:L complexes with labile metal ions, although [CuL1] and [NiL1] were observed as minor species, the latter characterized by a crystal structure analysis. A mononuclear complex formed with inert Co(III) was characterized by a crystal structure as the neutral 1:2 complex [Co(L1)(HL1)] with two ligands acting as tridentate ligands, one coordinated by the central pyridine and its two flanking deprotonated amido groups, and the other by the central pyridine, one amido and one terminal pyridine group, with the remaining poorly coordinating protonated amide remaining unbound along with other terminal pyridine groups. Fe(III) is known to form a symmetrical 1:2 complex, but that complex is anionic due to binding of all four deprotonated amido groups; the unsymmetrical neutral Co(III) complex converts into a symmetrical anionic species only on heating for hours in aqueous base in the presence of activated carbon.
