A bis(acetylacetonato-O,O′)(imidazole)nitrocobalt(III) coordination compound was synthesized and characterized toward photoswitching properties. The exists as two isomers, cis trans, depending on the relative arrangement of acetylacetone ligands chelating metal center. Crystals both isomers were obtained. form proven to be photoswitchable in solid state at room temperature also a lesser extent lower temperatures down 10 K, upon near-UV irradiation (365–405 nm LED light). Based IR...
The rare observation of transient Rh···Rh excimer formation in a single crystal is reported. estimated excited-state lifetime at 100 K 2 ns, which makes it the shortest-lived small-molecule species caught experimentally using laser-pump/X-ray-probe time-resolved Laue method. Upon excitation with 390 nm laser light, intermolecular distance decreases from 3.379(4) to 3.19(1) Å, and metal–metal contact gains more bonding character. On basis experimental results theoretical modeling, structural...
Two photoswitchable nickel(II) nitro coordination compounds and their copper(II) analogues are reported. In all these systems, the metal center is chelated by (N,N,O)-donor ligands containing either 2-picolylamine or 8-aminoquinoline fragments. The studied were thoroughly investigated using crystallographic spectroscopic techniques supplemented computational analysis. They easy to synthesize stable, undergo group isomerization reaction. Nevertheless, there significant differences between...

Two analogous photoswitchable square-planar nitrite coordination compounds of NiII and PdII with the (N,N,O)-donor (1-phenyl-3-(2'-picolylimino)prop-2-en-1-one) ancillary ligand, Ni-1a Pd-1a, are reported. The samples were thoroughly characterized (photo)crystallographically, spectroscopically, computationally. crystallizes in P1̅ space group one molecule comprising asymmetric unit, whereas Pd-1a tends to form polymorphic (Pd-1a Pd-1a′) solvatomorphic (with dichloromethane: Pd-1a-DCM...
The importance of transition-metal switchable compounds real-life applications is rapidly increasing, thus investigations nickel (II) organic complexes in which metal centre coordinated by molecular fragments that can exist multiple isomeric forms (e.g.NO2, SO2 , N2) cannot be overestimated.Hence, the current study was devoted to obtain novel promising photoswitchable materials characterized desired reversibility, high conversion percentage and stability.The designed model compound shown...
Smart engineering of new photoactive materials desired properties constitutes an important and increasingly urgent issue in modern chemical research.This is because such find multiple scientific commercial applications as photocatalysts, light emitters, biological markers, optoelectronic devices, etc. From a perspective, coordination compounds containing transition metal centres with d 8 -d 10 electronic configurations are among the most interesting functional systems this kind.Such prone to...
