Tetraaquabis(3,5-dihydroxybenzoato-O)nickel(II) trihydrate

H.-Y. Wang, S. Gao and S. W. Ng

Abstract: The covalently bonded monodentate carboxylate groups in the title compound, [Ni(C₇H₅O₄)₂(H₂O)₄]·3H₂O, are trans to each other; the octahedrally coordinated Ni atom lies on a pseudo-center of inversion that relates the carboxylate groups to each other as well as two coordinated water molecules to the other two. Extensive hydrogen bonding leads to the formation of a three-dimensional network.
