[2-(2,2′:4′,2′′-Terpyridin-6′-yl-κ²N¹,N^1′)benzoato-κO]manganese(II) trihydrate

In the title complex, [Mn(C₂₂H₁₄N₃O₂)₂]·3H₂O, the Mn^II ion is coordinated by two N,N′,O-tridentate 2-(2,2′:4′,2′′-terpyridin-6′-yl-κ²N¹,N^1′)benzoate ligands in a distorted cis-MnO₂N₄ octa­hedral geometry. In one ligand, the dihedral angles between the central pyridine ring, the other bonded pyridine ring, the terminal pyridine ring and the benzene ring are 14.3 (15), 18.3 (18) and 43.9 (16)°, respectively. The equivalent angles in the second ligand are 5.8 (18), 6.3 (18), and 47.0 (17)°, respectively. In the crystal, the complex molecules and lattice water molecules are linked by O—H...O and O—H...N hydrogen bonds, generating a three-dimensional network.

2-[(5-Methyl­thio­phen-2-yl)methyl­idene]malono­nitrile

There are two independent molecules in the asymmetric unit of the title compound, C₉H₆N₂S, which is an inter­mediate compound of a cardiovascular drug. The two molecules are nearly planar, displaying dihedral angles of 3.5 (2) and 5.7 (2)° between the thiophene ring and the malononitrile moiety. In the crystal, C—H...N inter­actions lead to the formation of a sheet structure that packs in a parallel fashion.
