cis-Dichloro­bis(1,10-phenanthroline)cobalt(II)

In the molxadecule of the title compound, cis-[CoCl2(C12H8N2)2], the CoII atom has a distorted octaxadhedral coordination formed by four N atoms from two 1,10-phenanthroline ligands and two Cl atoms. In the crystal structure, molxadecules are linked into a three-dimensional framework by C—H⋯Cl hydrogen bonds. The supraxadmolecular network is also consolidated by π–π stacking interxadactions.

Bis(4‐phenylpyridinium) tetrakis(nitrato‐κ2O,O′)stannate(IV)

The asymmetric unit of the title compound, (C11H9N)2[Sn(NO3)4], consists of a mononuclear complex anion and two non-coordinated 4-phenylxadpyridinium cations. The SnIV atom, lying on a twofold rotation axis, is coordinated by eight O atoms of four NO3− anions. This mononuclear complex is further extended into a supraxadmolecular network structure via non-classical hydrogen bonds between CH groups of cations and O atoms of neighbouring anions.
