Synthesis, crystal structure and Hirshfeld surface analysis of aqua­(3-meth­oxy­cinnamato-κO)bis­(1,10-phenanthroline-κ(2) N,N′)cobalt(II) nitrate

The title compound, [Co(C(10)H(9)O(3))(C(12)H(8)N(2))(2)(H(2)O)]NO(3) (I), crystallizes in the triclinic space group P [Image: see text] with a monomeric [Co(3-meo-cin)(phen)(2)(H(2)O)](+) cation and a nitrate anion (3-meo-cin = 3-meth­oxy cinnamic acid) in the asymmetric unit. The Co(II) ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms, the first from a meth­oxy cinnamate ligand and the second from a coordinated water mol­ecule, forming a distorted octa­hedral geometry. Discrete entities of the cation and nitrate anion are formed by water–nitrate O—H⋯O and phen–nitrate C—H⋯O hydrogen bonds. The components are further assembled into chains along the c-axis direction. Layers are than formed by slipped π–π stacking inter­actions parallel to the bc plane. The inter­molecular inter­actions in the crystal structure were qu­anti­fied and analysed using Hirshfeld surface analysis.
