MITCHELL GUSS AND HANS C. FREEMAN* Department of Inorganic Chemistry, University of Sydney, Sydney 2006, Australia (Received 26 January 1983; accepted 3 May 1983) Abstract. M,=434.19, monoclinic, C2/c, a= 12.488(2), b= 11.121(1), c= 14.526(2)/k, fl= 107.7 (1)°, V= 1921.5 (7)/k3, Z = 4, D,, = 1.51 (1), Dx= 1.501 gcm-3, 2(MoKct)=0.71069,~,, /t(Mo Ka) = 9.63 cm-', F(000) = 892, T= 291 K, R = 0.030 for 2096 unique reflections. The metal atom is octahedrally coordinated [Mn-N(imidazole) = 2.282 (2), 2.213 (6)/k; Mn--O(water)= 2.230 (2) AI. The Mn-O(water) bonds are longer and two Mn- N(imidazole) bonds are shorter than the corresponding bonds in [Mn(H20)6]2+ and [Mn(imidazole)6]2+ ions. The two remaining Mn-N(imidazole) bonds are similar 2+ in length to those in the [Mn(imidazole)6] ion. * Author to whom correspondence should be addressed. 0108-2701/83/081031-04501.50 Introduction.
