    Notes: Abstract Between April 1988 and July 1995, 11 children with a lymphangioma were treated with intralesional OK-432 injection. In 7 patients it was the primary therapy and total shrinkage of the lesion was obtained in 5 of them. Two patients did not respond and the children underwent surgery. Following incomplete surgical removal or recurrence of the lymphangioma, intralesional OK-432 injection was used as secondary therapy in 4 patients. Total regression was observed in 2 cases and marked regression in the 2 others. No serious side-effects except fever lasting for 2–3 days and slight tenderness with swelling of the lymphangioma for 3–4 days after the injection was noted. Local inflammatory reaction did not cause any damage to the overlying skin and did not lead to scar formation. Depending on the size, location, and anatomical relationship to the airway, intralesional injections of the lymphangiomas were performed under general anaesthesia and the children were observed for 24 h. There was no recurrence after follow up periods ranging from 2 months to 7 years. Conclusion Intralesional injection of OK-432 represents an alternative, safe and effective treatment for lymphangiomas. It can be used as the primary therapy, after partial surgical excision, or in recurrent lymphangiomas.

    Notes: Die Oberflächenspannung des Quecksilbers im höchsten Vakuum liegt zwischen dem Anfangswert und dem Endwert der Oberflächenspannung in Luft. Bei Zinn konnte eine Veränderung der Oberflächenspannung mit der Zeit im Vakuum von 5·10-5 mm Hg nicht festgestellt werden. Thallium wies eine Zunahme der Oberflächenspannung mit der Zeit im Vakuum von 10-5 bis 10-4 mm Hg auf. Aus diesen Feststellungen wurde geschlossen, daß dort, wo beim Quecksilber Veränderungen der Oberflächenspannung mit der Zeit vorliegen, die sich einstellenden Oberflächenspannungen sich als Resultierende zwischen den Einflüssen der Anordnung der Metallatome der Oberfläche und der ein- und angelagerten Gasatome ergeben.

    Description / Table of Contents: Mg2IrB2-x, a Magnesium Iridium Boride with a Structure Related to the W2CoB2-TypeThe new compound Mg2IrB2-x with a small homogeneity range determined approximately as 0,2 ≤ x ≤ 0,35 crystallizes monoclinically in the space group C2/m, Z=4 (lattice constants see Inhaltsübersicht). The structure which was solved by single crystal X-ray and powder neutron diffraction methods is related to the W2CoB2-type and contains distorted Mg4Ir2-prisms. The boron atoms are partly disordered. They are situated either inside the prisms forming pairs or with very short Ir-B distances (199 pm) on an elongated prism edge formed by two iridium atoms.
    Notes: Die neue Verbindung Mg2IrB2-x mit einem schmalen Homogenitätsbereich, der näherungsweise zu 0,2 ≤ x ≤ 0,35 bestimmt wurde, kristallisiert monoklin in der Raumgruppe C2/m, Z = 4. Bei x = 0,35 betragen die Gitterkonstanten a = 858,0(1) pm, b = 484,6(1) pm, c = 683,6(1) pm, β = 115°43′(1). Die Struktur, die mit Röntgen-Einkristall- und Pulver-Neutronenbeugungsmethoden bestimmt wurde, leitet sich vom W2CoB2-Typ ab und enthält verzerrte Mg4Ir2-Prismen. Die Boratome sind zum Teil fehlgeordnet. Sie befinden sich entweder innerhalb der Prismen und bilden Paare, oder sie liegen auf einer aufgeweiteten, aus zwei Iridiumatomen bestehenden Prismenkante, wobei sehr kurze Ir-B-Abstände ausgebildet werden (199pm).

    Description / Table of Contents: Reaction of Bis(2-mercaptoethyl)phosphines with Organotin Compounds. Molecular Structure of a Tin Containing Sixteen-membered RingThe reaction of bis(2-mercaptoethyl)phosphine with di-t-butyltin dimethoxide yields mixture of oligomers of the type [t-Bu2Sn(SCH2CH2)2Pr]n (R = Me, Ph) from which the trans-configurated dimers (n = 2) have been isolated. By the reaction with sulphur and selenium, respectively, these dimers were transformed to the corresponding thioxo and selenoxo derivatives.The sixteen-membered ring trans-[t-Bu2Sn(SCH2CH2)2P(S)Ph]2 crystallizes in the space group P21/n with the unit cell dimensions a 1350.9, b 1310.2, c 1500.3 pm, β 96.36° and does not exhibit any intramolecular Sn—P interaction: The 1,5-diorgano-1-chloro-5-elementa-1-stanna(IV)-bicyclo-[3.3.01,5]octanes R(Cl)Sn(SCH2CH2)2E (6, R = Ph, E = PPh; 7, R = Ph, E = NMe) have been prepared from the corresponding sodium dithiolates and phenyltrichlorostannane. The transannulare Sn—P and Sn—N interactions in 6 and 7 are confirmed by 31P and 119Sn NMR investigations.
    Notes: Die Reaktion von Bis(2-mercaptoethyl)phosphinen mit Di-t-butylzinndimethoxid liefert Mischungen von Oligomeren des Typs [t-Bu2Sn(SCH2CH2)2PR]n (R = Me, Ph), von denen die trans-konfigurierten Dimere (n = 2) isoliert wurden. Durch Reaktion mit Schwefel bzw. Selen wurden diese in die entsprechenden Thio- bzw. Selenoderivate überführt. Der Sechzehnring trans-[t-Bu2Sn(SCH2CH2)2P(S)Ph]2 4 kristallisiert in der Raumgruppe P21/n mit den Gitterkonstanten a 1350,9, b 1310,2, c 1500,3 pm und β 96,36°, er enthält keine intramolekularen Sn—P.-Wechselwirkungen. Die 1,5-Diorgano-1-chloro-5-element-1-stanna(IV)-bicyclo[3.3.01,5]-octaneR(Cl)Sn(SCH2CH2)2E (6, R = Ph, E = PPh; 7, R = Ph, E = NMe) wurden aus den entsprechenden Natriumdithiolaten und Phenyltrichlorstannan erhalten. Die transannularen Sn—P- und Sn—N- Wechselwirkungen in 6 und 7 werden durch 31P- und 119Sn-NMR-Untersuchungen bestätigt.
