    Description / Table of Contents: The reaction of zinc halides (ZnCl2, ZnBr2) or Zn(BH4)2 with LiBH4 or NaBH4 in ether or tetrahydrofurane yields LiZn(BH4)3, Li2Zn(BH4)4 or NaZn(BH4)3 respectively. The latter complex is also obtained by the reaction of NaZn(OCH3)3 or Na2Zn(OCH3)4 with diborane. Octakis(tetrahydridoborato)-trizincate K2Zn3(BH4)8 and BaZn3(BH4)8 are formed by treating Zn(BH4)2 with KBH4 or Ba(BH4)2.The 11B-nmr- and ir-spectra of the new complexes are recorded and discussed in terms of double hydrogen bridge bonding of BH4 groups to the central zinc atom.
    Notes: Die Umsetzung von Zinkhalogeniden (ZnCl2, ZnBr2) bzw. Zinkboranat (Zn(BH4)2) mit LiBH4 oder NaBH4 in Äther oder Tetrahydrofuran liefert LiZn(BH4)3, Li2Zn(BH4)4 bzw. NaZn(BH4)3. Natriumtriboranatozinkat fällt auch bei der Reaktion von NaZn(OCH3)3 oder Na2Zn(OCH3)4 mit Diboran an. KBH4 und Ba(BH4)2 reagieren mit Zn(BH4)2 zu den Octaboranatotrizinkaten K2Zn3(BH4)8 und BaZn3(BH4)8.Die 11B-Kernresonanz- und IR-Spektren der neuen Komplexverbindungen werden diskutiert. Danach sind die BH4-Gruppen über zwei Hybridwasserstoffatome an das Zinkatom gebunden.
