were isolated. Its crystal structure is made up from zigzag chains, propagating in [001], in which the Ni
2+
ions are linked alternatively by μ
2
-fumarato and bis-chelating fumarato bridging ligands. The Ni
2+
ion is coordinated in a deformed octahedral geometry by one chelating 1,10-phenanthroline ligand, one aqua ligand in a
cis
position with regard to both
N
-donor atoms and by two different fumarato ligands, each residing with its central C=C bond on an inversion centre, occupying the remaining coordination sites in a
fac
fashion. The chains thus formed are linked by O—H⋯O hydrogen bonds and π–π interactions between the aromatic rings of the phenanthroline ligands with a shortest ring centroid separation of 3.4787 (10) Å. |
