Description

Ammonium decamolybdodimetallates of the (NH4)n[M2Mo10C34(OH)4]·7H2O composition, where M=Cr3+ (n=6), Cu2+ (n=8), Ni2+ (n=8), are synthesized and investigated by X-ray diffraction, thermal gravimetric, IR spectroscopic methods for the first time. Compounds are crystallized in triclinic lattice with lattice parameters: a=10.68(2), b=9.46(2), c=7.97(2) A, α=75.12(3) Deg, β=96.82(3) Deg, γ=102.21(3) Deg, V=754.4(3) A3, ρcal=4.05 g/cm3, Z=1 for chromium compound; a=10.57(2), b=9.29(2), c=8.47(2) A, α=73.91(3) Deg, β=96.05(3) Deg, γ=104.71(3) Deg, V=854.3(3) A3, ρcal=3.68 g/cm3, Z=1 for copper compound, and a=10.96(2), b=8.95(2), c=7.40(2) A, α=71.76(3) Deg, β=97.04(3) Deg, γ=102.91(3) Deg, V=875.3(3) A3, ρcal=3.65 g/cm3, Z= 1 for nickel compound

Abstract (Russian)

Впервые синтезированы и исследованы рентгенографическим, термогравиметрическим и ИК-спектроскопическим методами декамолибдодиметаллаты аммония состава (NH4)n[M2Mo10C34(OH)4]·7Н2О, где М=Сr3+ (n=6), Cu2+ (n=8), Ni2+ (n=8). Соединения кристаллизуются в триклинной сингонии с параметрами элементарной ячейки: а=10.68(2), b=9.46(2), c=7.97(2) А, α=75.12(3) град, β=96.82(3) град, γ=102.21(3) град, V=754.4(3) А3, ρвыч=4.05 г/см3, Z=1 для соединения хрома; а=10.57(2), b=9.29(2), с=8.47(2) А, α=73.91(3) град, β=96.05(3) град, γ=104.71(3) град, V=854.3(3) А3, ρвыч=3.68 г/см3, Z=1 для соединения меди и а=10.96(2), b=8.95(2), с=7.40(2) А, α=71.76(3) град, β=97.04(3) град, γ=102.91(3) град, V=875.3(3) А3, ρвыч=3.65 г/см3, Z=1 для соединения никеля
