Large Single Crystals of Isomorphous Hexaaquametal(II) d-Camphor-10-sulfonates

Abstract

Novel hexaaquametal(II) bis(D-camphor-10-sulfonates) with Mn(II), Fe(II), and Co(II) ions were synthesized as large single crystals. During the crystallization process, suitable metal wires were used to induce crystallization. Crystals were analyzed by means of X-ray analysis, IR spectrophotometry, and solid state UV-vis spectroscopy. The obtained substances are stable in air, and their UV-vis spectra imply their potential use as optical filters and optical materials.

Water Exchange Reactivity and Stability of Cobalt Polyoxometalates under Catalytically Relevant pH Conditions: Insight into Water Oxidation Catalysis

“…Structural analysis of the average Co–OH 2 bond distances ( d Co–O = 2.116(6) Å in 1 and ≤2.085 Å in [Co(H 2 O) 6 ] 2+ ) , indicates that the oxo ligands in 1 have a weakening effect on the Co–OH 2 bond; however, our results show that this feature is not reflected by a significantly increased water exchange rate in 1 when compared with [Co(H 2 O) 6 ] 2+ (Table ). One possible explanation would be the stabilization of the water ligand in 1 through cluster-based hydrogen-bonding interactions.…”

Synthesis and spectroscopic properties of large single-crystals of Pb(II), Hg(II) and Sr(II) methanesulfonato 1D coordination polymers

“…As a continuation of ongoing studies of the optical properties of various metal salts of alkyl sulfonic acid [16][17][18], three compounds were prepared from the simplest possible alkyl sulfonate, methanesulfonate. The compounds 1-3 are obtained as crystalline solids in very good yields (81-87%).…”

“…In order to realize further research and to develop on previous studies [17][18][19], the physical properties of three newly synthesized crystalline compounds with methanesulfonate as the anion are presented herein. Since within the previous series of synthesized compounds, their purpose was not emphasized, possible applications of the newly synthesized compounds as wide-range, transparent and cheap optical materials are presented.…”

Syntheses, structures and luminescent properties of six divalent metal terephthalate coordination polymers based on three new flexible bis(imidazole) ligands

“…The splitting of the 3d levels transfers energy to the ligand which was accompanied by energy transfer in the UV-vis range of the electromagnetic spectrum. 24 Lower energy bands from 310 to 350 nm were assigned to metal-to-ligand charge-transfer (MLCT) transitions. 14…”
