Two crystal structures towards the discotic columnar mesophase of (1,4,8,11,15,18,22,25-octahexylphthalocyaninato)nickel. Erratum

The low-temperature apparatus used in this work [Helliwell, Deacon, Moon, Powell & Cook, Acta Cryst. (1997), B53, 231-240] was the Oxford Cryosystems Cryostream, and not as stated a cryo-cooling system manufactured by Oxford Instruments. Also, on p. 235, lines 8-10, right-hand column, should read '...for molecule (2), whilst two are approximately perpendicular to it. .. For molecule (1)...'. © 1997 International Union of Crystallography Printed in Great Britain - all rights reserved Acta Crystallographica Section B ISSN 0108-7681 © 1997
