Título: | Two-step synthesis of heterometallic coordination polymers using a polyazamacrocyclic linker |
Autor: | Aríñez-Soriano, Javier CSIC; Albalad, Jorge CSIC ORCID; Pérez-Carvajal, Javier CSIC ORCID; Imaz, Inhar CSIC ORCID; Busqué, Félix; Juanhuix, Jordi; Maspoch, Daniel CSIC ORCID | Fecha de publicación: | 2016 | Editor: | Royal Society of Chemistry (UK) | Citación: | CrystEngComm 18(22): 4196-4204 (2016) | Resumen: | A new macrocyclic linker 1,4,7,10-tetraazacyclododecane-1,7-bis(4-acetamidobenzoic)-4,10-diacetic acid (HL1) was synthesized and characterized. This linker was used to create two heterometallic coordination polymers following a two-step synthesis. This synthesis consisted of first combining this polyazamacrocyclic linker with Ni(ii) or Mn(ii) ions to obtain the corresponding metallomacrocyclic complexes showing non-coordinated carboxylic groups. In a second step, these metallated macrocycles were used as building units to construct two heterometallic Ni(ii)-Zn(ii) and Mn(ii)-Zn(ii) coordination polymers when combined with Zn(ii) ions. In addition, a third Zn(ii)-Zn(ii) coordination polymer could also be synthesized by direct mixing of HL1 with Zn(ii) ions. Interestingly, the Mn(ii)-Zn(ii) coordination polymer exhibits a reversible type-I >crystal-to-amorphous transformation> upon water sorption/desorption. | URI: | http://hdl.handle.net/10261/143183 | DOI: | 10.1039/C5CE02520F | Identificadores: | doi: 10.1039/C5CE02520F e-issn: 1466-8033 |
