    Description / Table of Contents: The Crystal Structure of a Bisaxial with tert-Butylacetylene Substituted Germanium Hemiporphyracinetrans-Bis(3,3-dimethyl-1-butyneyl) hemiporphyracine germanium crystallizes by sublimin furane in triclinic crystals with the space group P1 and the lattice constants a = 860.4, b = 960.7, c = 1141.6 pm; α = 74.01, β = 113.62, γ = 108.50°. The unit cell contains one centrosymmetric molecule, in which the germanium atom is surrounded in a distorted octahedral coordination by four nitrogen atoms of the hemiporphyracine ligand (Ge - N: 195.6 and 217.2 pm) and two carbon atoms of the tert-butylacetylene group (Ge - C: 193.8 pm). The germanium hemiporphyracine moiety is mostly planar.
    Notes: trans-Bis(3,3-dimethyl-1-butinyl)hemiporphyrazin-germanium kristallisiert beim Sublimieren in triklinen Kristallen, mit der Raumgruppe P1 und den Gitterkonstanten a = 860.4, b = 960.7, c = 1141.6 pm; α = 74.01, β = 113.62, γ = 108.50°. Die Elementarzelle enthält ein zentrosymmetrisches Molekül, in dem das Germaniumatom verzerrt oktaedrisch von 4 Stickstoffatomen des Hemiporphyrazinliganden (Ge - N: 195.6 und 217.2 pm) und 2 Kohlenstoffatomen der tert-Butylacetylengruppen (Ge - C: 193.8 pm) umgeben ist. Der Germaniumhemiporphyrazin-Teil ist weitgehend eben gebaut.

    Description / Table of Contents: Synthesis and Structure of Cyano(dihydrodibenzo[b,i][1,4,8,11]tetraazacyclotetradecinato)-cobalt(III)Cyano(dihydrodibenzo[b,i][1,4,8,11]tetraazacyclotetradecinato)cobalt(III) (CotaaCN) is formed by reaction of Cotaa with sodium cyanide and oxygen. CotaaCN crystallizes orthorhombic, space group P212121 with the cell dimensions a = 698.6 pm, b = 1466.2 pm, and c = 1553.7 pm, Z = 4. The compound is a pentacoordinated monomer with a Co—C distance of 182 pm. The IR spectrum of this monomeric compound exhibits a CN-valence frequency at 2116 cm-1.
