[Cu (CIaH27N4OE) CN]. ½C2H3N,[Cu (CN)-(pnao-H)]. ½CHaCN, orthorhombic, Fdd2, a= 18.993 (2), b= 32.352 (2), c= 11.799 (1),~, V--7250.0/~ 3, Mr= 381.48, Z= 16, Pcalc= 1.40 (1), Pobs= 1.41 (1) Mg m-3. Three-dimensional counter X-ray data were used to solve and refine the structure to a final R (F2) of 0.054 for 2600 independent reflec-tions. The structure consists of discrete monomeric square-pyramidal Cu complex molecules with a strong intramolecular hydrogen bond. The tt-amine-oxime ligand is quadridentate with an average Cu-N (amine) distance= 2.043 (3) A and Cu-N (oxime)= 1.978 (3) A. The cyanide ion is carbon bonded at the apical position with a Cu-C bond distance of 2.154 (5) A. The strong Cu-CN bond pulls the Cu2÷ ion out of the plane of the four N atoms by 0.499 (6),/k. The short intramolecular hydrogen bond of 2.475 (4)/k is not appreciably modified by the presence of CN-. The acetonitrile molecule is not coordinated to the Cun atom, but packs between the Cu complexes as solvent of crystallization.Introduction. The deep-purple crystals (Murmann & Monzyk, 1978) were consistently twinned when grown from aqueous media but gave satisfactory crystals from anhydrous acetonitrile. They crystallize with primarily {010},{011}, and {110} facial development. The crystal selected was semi-spherical and had a volume of about 0.023 mm3. The space group and cell dimensions were first determined by precession film data, and the final cell dimensions were obtained with a Picker diffractometer from a least-squares refinement of the
