Abstract

Two pairs of isomorphic molecular phosphonates are reported. The first isomorphic pair involves the co-crystals [{Co2(η1-DMPzH)4(Cl3CPO3)2}{Co(η1-DMPzH)2Cl2}2](toluene)2 [1] and [{Zn2(η1-DMPzH)4(Cl3CPO3)2}{Zn(η1-DMPzH)2Cl2}2](toluene)2 [2] while the second isomorphic pair is {Co2(η1-DMPzH)2Cl2(Cl3CPO3)2}(HNEt3)2 [3] and {Zn2(η1-DMPzH)2Cl2(Cl3CPO3)2}(HNEt3)2 [4]. These have been prepared by multi-component reactions involving normal solution-state synthesis at room temperature. Change of reaction solvent from acetonitrile to methanol affords change of products from 1 and 2 to 3 and 4.
