Constructing an unprecedented {MnII38} matryoshka doll with a [Mn18(CO3)9] inorganic core and magnetocaloric effect†
Abstract
An unprecedented inner [Mn18(CO3)9] inorganic core and [Mn20] metal–organic periphery compose a high-nuclearity homometallic single-valent {MnII38} molecular aggregate with a [Mn6] ⊂ [Mn12] ⊂ [Mn8] ⊂ [Mn12] matryoshka doll-like skeleton that displays a significant magnetocaloric effect (MCE).
