(5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetra­azacyclo­tetra­decane-1,8-diacetato)nickel(II) tetra­hydrate

The Ni atom in the title compound, [Ni(C₂₀H₃₈N₄O₄)]·4H₂O, is chelated by four N atoms of the macrocycle and also covalently bonded to two carboxyl­ate groups, in a cis-N₄O₂Ni octa­hedral environment. The mononuclear complex inter­acts with the solvent water mol­ecules to form a three-dimensional network structure.

(5,5,7,12,12,14-Hexameth­yl-1,4,8,11-tetra­aza­cyclo­tetra­deca­ne-1,8-diacetato)cobalt(II) tetra­hydrate

The Co atom in the title compound, [Co(C₂₀H₃₈N₄O₄)]·4H₂O, is chelated by the four N atoms of the macrocycle and also covalently bonded to two carboxyl­ate O atoms in a cis-N₄O₂Co octa­hedral environment. The mononuclear mol­ecule inter­acts with the non-coordinated water mol­ecules by way of O—H...O inter­actions to form a three-dimensional network.

1,4,8,11-Tetra­kis(carboxy­meth­yl)-5,5,7,12,12,14-hexa­meth­yl-1,4,8,11-tetra­azoniacyclo­tetra­deca­ne tetra­chloride octa­hydrate

The crystal structure of the centrosymmetric title compound, C₂₄H₄₈N₄O₈⁴⁺·4Cl^-·8H₂O, consists of a 14-membered meth­yl-substituted C₁₀N₄ cationic ring which inter­acts with the chloride ions and water molecules of crystallization to give a three-dimensional hydrogen-bonded network structure.
