Mixed sandwich complexes table

Interestingly, the structural parameters for the individual pz and porphyrin subunits of the mixed sandwich complex are indistinguishable. Selected bond lengths and angles for sandwich compounds (29), the heteroleptic system (30), and the homoporphyrin analogue are listed in Table VI (33). 

The solution behavior of these mixed sandwich complexes was studied by H and 13C H) NMR techniques. Due to the Cs symmetry or lower of these mixed complexes the expected number of resonances should be 2 (Q) or 4 (lower symmetry). In Table 2 the H and i3C H) NMR pyrrolyl resonances are indicated. All mixed sandwich complexes...

Some of the known mixed sandwich complexes are shown in Table 22. These complexes may be prepared by a variety of routes which are exemplified below. 

A coffeehouse setting with cheery walls and oddly shaped tables, Naked Earth serves complex food in a simple setting. For lunch, try their no-tuna sandwich - tofu, celery, onion, sesame seed, seaweed, and a mix of herbs and spices on your choice of bread. Someone s finally invented a well-textured tuna sandwich that doesn t taste fishy Another sandwich option is the sun-dried tomato hummus. Sandwiches are served with sprouts, lettuce, tomatoes and a side of homemade cole slaw made with red cabbage and tofu mayonnaise. They also offer a daily soup and salad special. On my visit, the lasagna looked excellent - layered seitan and tofu ricotta with peppers and mushrooms.
