A dual-functional organic-inorganic hybrid (BEDT-TTF)2Cu2(HCOO)5 (1) (BEDT-TTF=bis(ethylenedithio)tetrathiafulvalene) was obtained through the electrochemical oxidation of neutral BEDT-TTF in the presence of an ammonium salt of the one-dimensional copper-formate framework [(C2H5)3NH]2Cu2(HCOO)5 in a C6H5Cl-C2H5OH solution. Compound 1 was composed of organic donor BEDT-TTF+0⋅5 in a θ-phase arran...

Materials and methods: Twenty laminate veneers were prepared prefabricated metal dies upper right central incisors with incisal lap preparation design using CAD-CAM system from materials (Zircad Prime "ZP", DD cubeX2 ML "DD", CopraSupreme Symphony "WP", IPS E.max CAD), ...
The crystal structure of the title compound, poly[bis-(tri-methyl-ammonium) hexa-μ(1,1)-azido-tetra-azido-tricobalt-ate(II,III)], [(CH(3))(3)NH](2)[Co(II)Co(III) (2)(N(3))(10)], consists of anionic chains [Co(II)Co(III) (2)(N(3))(10)](2-) extending parallel to the c axis and [(CH(3))(3)NH](+) counter-cations situated between the chains. In the anionic chain, one tetra-hedrally coordinated Co(II...
The crystal structure of bis(triethylammonium)c/o5o-decahydrodecaborate [bis(triethylammonium)decaboranate(lO)], [(CaHs^NHMBioHio], was determined and refined (space group Pmmn, no. 59, a = 989.7, b = 1333.7, c = 903.7 pm). The compound is a versatile starting material for many substances containing the [BioHio]2entity and its derivatives. The c7oso-[BioHio]2cluster is a bicapped square antipri...
Differential scanning calorimetry, the temperature dependence of proton and deuteron lineshapes and spin-lattice relaxation times are reported for the isotopic species CH 3 NH 3 C10 4 , CD 3NH 3C104 and CH 3ND 3C104 of monomethylammonium Perchlorate. The data confirmed the existence of three different phase modifications in monomethylammonium Perchlorate and its selectively deuterated analogues...
