So it would be tin(IV) selenide or stannic selenide. The structure is two-dimensional and consists of one SnSe2 sheet oriented in the (0, 0, 1) direction. The roman numeral is the oxidation of the metal in the ionic compound. ›› SnSe2 molecular weight. All Sn–Se bond lengths are 2.75 Å. Se2- is bonded in a distorted T-shaped geometry to three equivalent Sn4+ atoms.

Metals that have more than one oxidation state must have a roman numeral. SnSe2 is tin selenide. Tin selenide, also known as stannous selenide, is an inorganic compound with the formula (SnSe), where Tin has a +2 oxidation state. This compound is also known as Tin(IV) Selenide. Naming Ionic Compounds Practice Worksheet Name the following ionic compounds, 4) 6) 9) 10) (Ill) Cu3P (tv) SnSe2 NaF Wnte the formulas for the fol/ow/ng compounds 11) 13) 15) 16) 20 berytlium chloride e vanadium (IV) carbonate tin (Il) nitrite cobalt (Ill) oxide lead (Il) sulfate vanadium (V) sulfide chromium (Ill) hydroxide lithium Iodide A B; Iron(III) Acetate: Fe(C2H3O2)3: Iron(III) Hydrogen Carbonate: Fe(HCO3)3: Iron(III) Hydroxide: Fe(OH)3: Iron(III) Nitrate: Fe(NO3)3: Iron(III) Permanganate: Fe(MnO4)3 in binary compounds like this you name the metal (including its oxidation state in this case) and the ending of the non-metal is dropped and "ide" added. A theoretical study is presented on the electronic structure of some two-dimensional metal chalcogenides that are of great interest as host lattices for the intercalation of metallocenes. Vanadium(IV) carbonate has Vn in the +4 oxidation state, equivalent to V4+. Selenium is in group 6 so will form a 2- ion, so the tin is 2+, and the name is. PbS (select) (select) c. SnF4 (select) (select) 12 Be sure to answer all parts. Similarly, what compound is SnSe2? The name of the compound then is Tin(IV) selenide. Hereof, how do you name an ionic compound? As Se is in group 6 it normallty has a valency of 2 and can form the Se2- ion. SnSe2 is trigonal omega structured and crystallizes in the trigonal P-3m1 space group. tin (II) selenide, or stannous selenide This means that if this is an ionic compound tin must have a valency of 4 (4+) to balance the two Se2- ions. For binary ionic compounds (ionic compounds … Sn4+ is bonded to six equivalent Se2- atoms to form edge-sharing SnSe6 octahedra. 8 01:45:36 Name each ionic compound. Convert grams SnSe2 to moles or moles SnSe2 to grams. Molar mass of SnSe2 = 276.63 g/mol. The periodic Hartree−Fock calculations with a posteriori correction for the correlation energy were carried out for the layer structures of SnS2, SnSe2, ZrS2, and TaS2.
