(2) C 21H23NO, Mr=30542, monoclinic, P2I/c, a = 6.513 (2), b = 10.554 (3), c= 23.455 (6),Å, ? = 91.95(3) °, V= 1611.1 (8)Å3, Z=4, Dx =126 g cm-3, ?(Mo K?) = 0.71069 Å, ? = 0.71 cm-l, F(000) = 656, T = 296 K, R = 0.058 for 1722 unique observed reflections [I>3?(I)]. (I) Bis{(1-adamantyl)[( 2-oxo- 1 H-naphth- 1 -ylidene)methyl]aminato}- copper(II), [Cu(C21H22NO) 2], Mr=67238, monoclinic,P2i/a, ?=18139(4), ?=10.227(3), c = 19.543 (5) A, /3 = 100.66 (2) °, V= 3563 (3) Å 3, Z = 4, Dx = 1.26 g cm -3, ?(Cu K?) = 1.54178 Å, ? = ll'14cm -1, F(000)= 1428, T=296K, R=0.056 for 3381 unique observed reflections [I>3?(I)]. (II) Bis{(2-adamantyl)[(2-oxo- 1H-naphth- 1-ylidene)- methyl]aminato}copper(II), [Cu(C21H22NO) 2], Mr = 672.38, triclinic, P1, ? = 11.854 (4), ? = 13.688 (4), c = 10.530 (2) Å, ? = 9775 (2), ? = 100.66 (2), ? = 10480 (2) °, V = 1616 (2) Å 3, Z= 2, Dx = 134 g ClT1-3, ?(Cu K?) = 154178 Å, ? = 1226 cm -1, F(000) = 710, T = 296 K, R = 0036 for 3498 unique observed reflections [I> 30-(I)]. In the crystal, state both ligands (1) and (2) are in the keto-amine tautomeric form. For the copper complexes (I) and (II), the geometry around the metal atom is distorted square planar, (I) being more distorted than (II). The angles between the chelate-ring planes in complexes (I) and (II) are 55.8 and 26.1 °, respectively. ©1992 International Union of Crystallography.
