Structure of magnesiumphthalocyanine complexes
Magnesiumphthalocyanine (MgPc; blue pigment) has attracted attention as a material useful for laser printers because of its near IR absorption. Two kinds of six-coordinate MgPc complexes have been grown from solution and their structures have been analyzed: MgPc/(H2O)2 (N-methyl-2-pyrrolidone)2 (crystal 1) and MgPc/(2-methoxyethanol)2 (crystal 2). The crystal data of crystal 1 are: MgPc/(H2O)2(NMP)2, Mr = 773.15, monoclinic, P21/n, a = 6.876(2) Å, b = 21.427(4) Å, c = 12.994(6) Å, β = 102.20(2)°, V = 1871(1) Å3, Z = 2, Dx = 1.375, Dm = 1.38 Mgm-3, graphite-monochromated MoK α, λ = 0.7107 Å, F(000) = 812.00, μ = 1.07 mm-1, T = 296 K, R = 0.074 for 1606 reflections. The crystal data of crystal 2 are: MgPc/(CH3OCH2CH2OH)2, Mr = 689.03, monoclinic, P21/n, a = 12.37(1) Å, b = 8.078(6) Å, c = 17.974(9) Å, β = 109.70(7)°, V = 1690(2) Å3, Z = 2, Dx =1.354, Dm = 1.37 Mgm -3, graphite-monochromated MoKα, λ = 0.7107 Å, F(000) = 720.00, μ = 1.08 mm-1, T = 296 K, R = 0.080 for 1407 reflections. In both complexes, the MgPc skeleton is found to be deformed as characterized by the molecular symmetry of Ci in contrast to D4h assumed for MgPc in the free space.
