The triplet excited state of a new crystalline form of a tetranuclear coordination d10–d10-type complex, Ag2Cu2L4 (L = 2-diphenylphosphino-3-methylindole ligand), containing AgI and CuI metal centers has been explored using the Laue pump–probe technique.
The structure of the triplet excited state of a new crystalline form of a tetranuclear coordination d10−d10-type complex, containing AgI and CuI metal centers, has been determined using the Laue pump−probe synchrotron technique. The results show a pronounced shortening of metal−metal contacts in the complex and a considerable strengthening of the argentophilic interaction on excitation.
