Perilaku Solvatochromic dan Pengaruh Substituen pada Serapan Elektronik Komplek Arenatrikarbonilkromium(0)
ABSTRACT: A number of
arenetricarbonylchromium(0) complexes, [(η6-arene)Cr(CO)3], in which arene =
benzene, chlorobenzene, phenyltrimethylsilane, and acenaphthene were
synthesized. Electronic absorptions of these complexes were recorded in various
solvents, ranging from polar to non polar ones; i.e. methanol, methylene
chloride, chloroform, benzene, and isooctane. These chromium tricarbonyl
complexes show lowest electronic absorption in the energy range of 313 - 320
nm, with relatively high intensity (ε = 0,9 - 2,0 x 104 M-1cm-1). Detailed
discussion of the solvent and substituent effect on electronic absorption of
these complexes are presented in this article.
Keywords: solvatochromic and
substituent effect, chromium tricarbonyl complexes, electronic absorption
