“…There is a range of SNe II models available in the literature. In the present situation, there are large differences in the predicted yields since there is a wide variety of input physics (e.g., criterion for convection, reaction rates, and the way to initiate the shock wave) (Aufderheide et al 1991;Gibson et al 1997).…”

“…The bounds for SNe II progenitors are taken to be m l = 10M ⊙ and m u = 50M ⊙ , respectively, and an IMF slope x = 1.35 (Salpeter 1955) is adopted throughout. While this slope is of prime importance for arguments concerning the absolute mass of elements in the ICM (e.g., , it is less so for abundance ratios (Gibson et al 1997).…”

“…In fact, Ishimaru & Arimoto (1997) concluded that a SNe Ia iron contribution of 50% or higher to the ICM enrichment could not be ruled out and might be favored by the observations. In the end, Gibson et al (1997) pointed out the large uncertainties of the adopted massive star physics and uncertainties in the resulting SNe II's chemical composition, which make it impossible to determine the contribution of SNe Ia to the iron enrichment of ICM. As a result, we have no way of estimating the contribution of SNe Ia to the ICMs.…”

“…Gibson et al (1997) insist that there would appear to be no escape from the fact that the sulfur abundances are at odds with a SNe II-dominated origin to the ICM iron abundance (although the uncertainties are large). This appears to be entirely independent of adopted SNe II yields (Gibson et al 1997). Quantitatively, the observed ratio S/Fe favors the ICM SNe Ia iron fractional contribution to be larger than 80%.…”

The origin of the chemical composition of the intracluster medium (ICM) is discussed in this paper. In particular, the contribution from Type Ia supernovae (SNe Ia) to the ICM enrichment is shown to exist by adopting the fitting formulas which have been used in the analysis of the solar system abundances.Our analysis means that we can use the frequency of SNe Ia relative to SNe II as the better measure than M Fe,SNIa /M Fe,total for estimating the contribution of SNe Ia. Moreover, the chemical compositions of ICMs are shown to be similar to that of the solar system abundances. We can also reproduce the sulfur/iron abundance ratio within a factor of 2, which means that the abundance problem of sulfur needs not to be emphasized too strongly. We need more precise observations to conclude whether ICMs really suffer the shortage problem of sulfur or not.Subject headings: intracluster medium (ICM): individual (Abell 496, Abell 1060, Abell 2199, AWM 7)-X-rays-Supernovae

This article presents a concise overview on the chemistry of organoantimony compounds containing one or more Sb–C bonds. It deals with homoleptic molecules where Sb is bonded exclusively to organic groups R, for example tri‐ or pentorganyls of antimony, and with heteroleptic derivatives where R n Sb groups ( n = 1, 2, 4) are bonded to other elements. Not only compounds with single bonds between Sb and C but also molecules with double bond character are considered.
