ORTEP representations of (a) the aluminate component of compound 17 and (b) compound 18 (30 % probability ellipsoids). Hydrogen atoms and iso‐propyl carbon atoms, in both structures, and a disordered molecule of benzene solvent in 18 are omitted for clarity. Selected bond lengths [Å] and angles [°]: (17) Al1−O1 1.7637(16), Al1−N1 1.8997(18), Al1−N2 1.889(2), Al1−34 1.984(3); O1−Al1−N1 109.88(8), O1−Al1−N2 106.51(8), O1−Al1−C34 102.23(10), N1−Al1−C34 113.76(10), N2−Al1−N1 110.75(8), N2−Al1−C34 113.10(10); (18) Al1−N1 1.8085(17), Al1−N2 1.8200(16), Al1−C31 2.125(2), Al1−C32 2.123(2), Ca1−N3 2.3437(17), Ca1−N4 2.3831(18), Ca1−C31 2.7107(19), Ca1−C32 2.804(2), Ca1−C33 2.818(2), Ca1−C34 2.753(2), Ca1−35 2.693(2), Ca1−C36 2.695(2), Ca1−C37 2.706(2), Ca1−C38 2.698(2); N1−Al1−N2 119.27(8), N3−Ca1−N4 79.34(6).
