Crystal structure, solvothermal synthesis, thermogravimetric studies and DFT calculations of a five-coordinate cobalt(II) compound based on the N,N-bis­(2-hy­droxy­eth­yl)glycine anion

The reaction of CoCl(2)·6H(2)O, N,N-bis­(2-hy­droxy­eth­yl)glycine and tri­ethyl­amine (Et(3)N) in ethanol solution under solvothermal conditions produced crystals of [N,N-bis­(2-hy­droxy­eth­yl)glycinato]chloridocobalt(II), [Co(C(6)H(12)NO(4))Cl]. The Co(II) ion is coordinated in a slightly distorted trigonal–bipyramidal environment which is defined by three O atoms occupying the equatorial plane and the N and Cl atoms in the apical sites. In the crystal, two types of O—H⋯O hydrogen bonds connect the mol­ecules, forming a two-dimensional network parallel to (001). The mol­ecular structure of the title compound confirms the findings of FTIR, elemental analysis, ESI–MS analysis and TG analysis. By using the density functional theory (DFT) (B3LYP) method with 6-31G(d) basis set, the molecular structure has been calculated and optimized.
