N2  - A low-temperature single-crystal X-ray structure determination of the 1 : 1 adduct of copper(II) nitrate with 2,2&#8242;-diphenyl-4,4&#8242;-bithiazole (L) shows it to be a molecular complex with L behaving as a symmetrical N,N&#8242; chelate, and the nitrate groups as unsymmetrical O,O&#8242; chelates: [LCu(O2NO)2]. Two polymorphs, both monoclinic P21/c, have been obtained from acetonitrile (&#8216;&#945;&#8217;) and methanol (&#8216;&#946;&#8217;), respectively, with one molecule, devoid of crystallographic symmetry, in the asymmetric unit of each structure. The copper environments are distorted planar four-coordinate, cis-N2CuO2 (Cu&#8211;N 2.011(1), 1.973(1), Cu&#8211;O 1.995(1), 1.962(1) &#197;), &#8216;in-plane&#8217; angle sum &#931; 369.5&#176;, with longer trans, axial contacts (Cu&#8211;O 2.455(1), 2.458(2) &#197;) for the &#945;-form; respective values are 1.995(5), 1.991(4), 1.997(4), 1.973(3) &#197;, 360.4&#176;, 2.500(4), and 2.396(4) &#197; for the &#946;-form.
