New 2D coordination polymers containing both bi- and tri-dentate dicyanamide bridges and intercalated phenazine

The isomorphous structures of M(dca)2(H2O)·phz [M = Co, Ni; dca = dicyanamide, N(CN)2−; phz = phenazine] contain phz molecules intercalating between 2D M(dca)2(H2O) sheets containing bi- and tri-dentate dca ligands; the Ni complex displays long-range order (Tc = 5.7 K).
