Cis-Aqua-bis-(di-2-pyridyl-amine-?N,N')iodidomanganese(II) iodide.

ABSTRACT: The asymmetric unit of the title compound, [MnI(C(10)H(9)N(3))(2)(H(2)O)]I, contains a cationic Mn(II) complex and an I(-) anion. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)IO octa-hedral environment defined by four N atoms of the two chelating di-2-pyridyl-amine (dpa) ligands, one I(-) anion and one O atom of a water ligand. As a result of the different trans effects of the I, N and O atoms, the Mn-N bond trans to the I atom is slightly longer than the Mn-N bond trans to the N or O atoms. The dpa ligands are not planar, with dihedral angles between the two pyridine rings of 26.2?(4) and 26.5?(4)°. The complex cations are stacked in columns along the a axis and are linked to the anions by inter-molecular O-H?I and N-H?I hydrogen bonds.

Bis(di-2-pyridyl-amine-?N,N')bis-(thio-cyanato-?N)nickel(II).

Project description:The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H?S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak ?-? inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777?(4)?Å], forming a three-dimensional assembly.

In the crystal, the building blocks are connected by N-H?N, O-H?N, N-H?O and O-H?O hydrogen bonding into a two-dimensional network parallel to (001).
