 Title      
 Abstract    Single crystals of (Me3Sn)3CCN were obtained by the reaction of tris(trimethylstannyl)amine with boiling acetonitrile in the presence of potas­ sium fluoride and trimethylarsane. The compound has been characterized by IR spectroscopy and by a crystal structure determination. Space group

C orreo 962, In attem pts to incorporate the L i(I) cation into the C a(II) position s o f the fluoroapatite lattice it has been sh ow n that the unit cell b eco m es increasingly distorted with the increase o f lithium concentration. C rystallographic data have been obtained from X-ray pow d er data. The infrared spectra o f th ese su bstitu ted apatites sh ow that the Li(I) incorporation has a n egligible effect on the strength o f the P-O bonds.

 Title    Crystal Structure, Vibrational Spectra and Thermal Analysis of Bis(saccharinato)bis(pyridine)zinc(II)  
 Abstract    The crystal structure of [Zn(sac)2(py)2] has been de termined by single-crystal X-ray diffrac-tometry. It crystallizes in the monoclinic space group C2/c with Z = 4. We propose and discuss an assignment of its IR and Raman spectra, compatible with the structural characteristics. Its thermal behavior was investigated by means of TG and DTA methods. Some comparisons with related compounds are made.

 Title    Synthese und Reaktivität von 7-Triphenylstannyl-a-am inobuttersäure- derivaten  
 Abstract    Ph3SnCH2CH 2C H (NHCOOCH 2P h)COOCH3 (1) is synthesized by hydrostannation of methyl N-(benzyloxycarbonyl)vinylglycinate with Ph3SnH. The reaction o f 1 with HC1 in CH 3OH and with bromine in CHC13 yields the halostannylsubstituted compounds Ph3_"X,?SnCH2CH 2C H(NHCOOCH 2Ph)C OOCH3 (2 -4) (n = 1, 2; X = Cl, Br). By sapo­ nification with one equivalent of NaOH and subsequent acidification with HCl 1 is transformed into the free acid Ph3SnCH2C H 2C H(NHCOOCH2Ph)COOH (5) that undergoes cyclization into the 1,2-oxastanninane 6 with intramolecular elimination of benzene. IR, NMR data and the determination of the crystal structure of Ph2BrSnCH2CH2CH(NHCOOCH2Ph)COOCH3(3) reveal for 2 and 3 an intramolecular coordination of the N C (0)0-group at the tin atom to form a seven-membered ring.
