The combination of cobalt, 3,5-di-tert-butyldioxolene (3,5-dbdiox) and 1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane (tpch) yields two coordination polymers with different connectivities, i.e. a one-dimensional zigzag chain and a two-dimensional sheet. Poly[[bis(3,5-di-tert-butylbenzene-1,2-diolato)bis(1,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-yl-3-olato)[μ-1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane]cobalt(III)]-ethanol-water 1/7/5], {[Co(CHO)(CHNO)]·7CHOH·5HO} or {[Co(3,5-dbdiox)(tpch)}·7EtOH·5HO}, is the second structurally characterized example of a two-dimensional coordination polymer based on linked {Co(3,5-dbdiox)} units. Variable-temperature single-crystal X-ray diffraction studies suggest that catena-poly[[[(3,5-di-tert-butylbenzene-1,2-diolato)(1,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-yl-3-olato)cobalt(III)]-μ-1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane]-ethanol-water (1/1/5)], {[Co(CHO)(CHNO)]·CHOH·5HO} or {[Co(3,5-dbdiox)(tpch)]·EtOH·5HO}, undergoes a temperature-induced valence tautomeric interconversion.
钴、3,5-二叔丁基二氧戊环（3,5-dbdiox）和1-羟基-1,2,4,5-四（吡啶-4-基）环己烷（tpch）的组合产生了两种具有不同连接性的配位聚合物，即一维之字形链和二维片层。聚[[双（3,5-二叔丁基苯-1,2-二醇根）双（1,5-二叔丁基-4-氧代环己-2,5-二烯-1-基-3-醇根）[μ-1-羟基-1,2,4,5-四（吡啶-4-基）环己烷]钴（III）]-乙醇-水1/7/5]，{[Co(CHO)(CHNO)]·7CHOH·5HO} 或 {[Co(3,5-dbdiox)(tpch)}·7EtOH·5HO}，是基于连接的{Co(3,5-dbdiox)}单元的二维配位聚合物的第二个结构表征实例。变温单晶X射线衍射研究表明，链状聚[[[(3,5-二叔丁基苯-1,2-二醇根)(1,5-二叔丁基-4-氧代环己-2,5-二烯-1-基-3-醇根)钴（III）]-μ-1-羟基-1,2,4,5-四（吡啶-4-基）环己烷]-乙醇-水（1/1/5）]，{[Co(CHO)(CHNO)]·CHOH·5HO} 或 {[Co(3,5-dbdiox)(tpch)]·EtOH·5HO}，经历了温度诱导的价互变异构体相互转化。
