- The reaction of one equivalent Co(NCS)$_{2}$ with four equivalents of urotropine (hexamethylenetetramine) in ethanol leads to the formation of two compounds, namely, bis(ethanol-$\kappa$O)bis(thiocyanato-$\kappa$N)bis(urotropine-$\kappa$N)cobalt(II), [Co(NCS)$_{2}$(C$_{6}$H$_{12}$N$_{4}$)$_{2}$(C$_{2}$H$_{6}$O)$_{2}$] ($\textbf{1}$), and tetrakis(ethanol-$\kappa$O)bis(thiocyanato-$\kappa$N)cobalt(II)–urotropine (1/2), [Co(NCS)$_{2}$(C$_{2}$H$_{6}$O)$_{4}$]$\cdot$2C$_{6}$H$_{12}$N$_{4}$ ($\textbf{2}$). In $\textbf{1}$, the Co cations are located on centers of inversion and are sixfold coordinated by two terminal N-bonded thiocyanate anions, two ethanol and two urotropine ligands whereas in $\textbf{2}$ the cobalt cations occupy position Wyckoff position c and are sixfold coordinated by two anionic ligands and four ethanol ligands. Compound $\textbf{2}$ contains two additional urotropine solvate molecules per formula unit, which are hydrogen bonded to the complexes. In both compounds, the building blocks are connected via intermolecular O—H$\cdots$N ($\textbf{1}$ and $\textbf{2}$) and C—H$\cdots$S ($\textbf{1}$) hydrogen bonding to form three-dimensional networks.
