The crystal structures of the Mg(NCS)2and Ca(NCS)2complexes withN,N,N′N′-tetracyclohexyl-3-oxapentanediamide are discussed: (1) (C28H48O3N2)2·Mg(NCS)2,Mr=1061.9, monoclinic, space groupP21/n,a=14.048(4),b=24.672(7),c=19.481(6) Å,β=78.79(2)°,V=6623.1 Å3,Z=4,dm=1.09,dx=1.06g cm−3,R=0.164 for 2350 unique diffractometer data; (2) (C28H48O3N2)3·Ca(NCS)2,Mr=1538.4, monoclinic, space groupP21(No. 4),a=14.470(3),b=19.334(5),c=17.082(4) Å,β=103.72(1)°,V=4642.6Å3,Z=2,dm=1.11,dx=1.10g cm−3,R=0.059 for 4596 unique diffractometer data. Compound (1) is an octahedral Mg2+complex in which three O atoms of one ligand molecule and the two carbonyl O atoms of the other together with the N atom of a thiocyanate ion occupy the coordination sites. In complex (2) the Ca2+ions are nine-coordinated by the O atoms of three ligand molecules.
