3D networks constructed using both coordinative and hydrogen bonding: synthesis, structure and magnetic properties of M(tcm)2(H2O)2·Me4pyz, M⊕=⊕Co, Ni

Abstract

One-dimensional coordination polymer chains of M(tcm)2(H2O)2 (M⊕=⊕Co, Ni; tcm⊕=⊕tricyanomethanide, C(CN)3−, Me4pyz⊕=⊕tetramethylpyrazine) are linked into 3D networks by hydrogen bonding between the chains and the intercalated Me4pyz molecules, and between the chains themselves. Very weak magnetic coupling is observed for the high-spin d7 and d8 ions with no evidence of long-range order.
