    Notes: Abstract Average data for igneous and/or metaigneous rocks and soils from seven lunar sites are presented. There are compositional similarities between Apollo 11 and Luna 16 eastern maria, Ap 12 and 15 western maria and between Ap 16 and L 20 highlands. Subtle differences do exist between the paired mare sites and the two highland sites and striking differences between the eastern and western maria. Chondritic normalized REE (rare earth element) patterns for igneous rocks and soils from all sites range from 7-350 generally with negative Eu anomalies. Anorthositic gabbroes to anorthosites, presumably highland material, exhibit a positive Eu anomaly. The REE patterns or Sr isotopic ratios suggest two lava flows each for the L 16 and Ap 14 sites, at least four lava flows for the Ap 11 and 12 site and about six for the Ap 15 site. Paucity of lunar andesites suggests rather limited lunar chemical differentiation. Norite-KREEP is a prominent component at Ap 12, 14 and 15, less at Ap 11 and 16 and L 16 and apparently very low at the L 20 highland site. Derivation of lunar soils can be best explained using multi-component mixing systems. Characterization of meteoritic impacting bodies is also observed in addition to a steady state veil of 1.9% carbonaceous Cl like material in soils. Interelement correlations impose constraints on the primitive composition of the Moon and on magmatic processes like selective volatilization.

    Description / Table of Contents: Methyl Dichlorophosphates of Tin and LeadThe compounds (CH3)3M(O2PCl2) (I), (M = Sn, Pb) and (CH3)2Sn(O2PCl2)2 (II), formed by the reaction of the corresponding methyltin and methylleadchlorides with P2O3Cl4 are described. The IR and Mössbauer spectra suggest that the tin compounds are polymerized through O—P—O bridges, whereby (I) and (II) contain metal atoms with coordination numbers five (D3h) and six (D4h), respectively.
    Notes: Darstellung und Eigenschaften der durch Umsetzung von P2O3Cl4 mit den entsprechenden Methylzinn- und Methylbleichloriden gebildeten Dichlorophosphate (CH3)3M(O2PCl2) (I), (M = Sn, Pb) und (CH3)2Sn(O2PCl2)2 (II) werden beschrieben. Aus Infrarot- und Mössbauer-Spektren geht hervor, daß die Verbindungen über O—P—O-Brücken zu Polymeren verknüpft sind, was für I zu Fünffachkoordination am Metallatom (D3h), für II zur Sechsfachkoordination führt (D4h).
