چکیده
In the title compound, [Mo(C(37)H(53)N(3))(CO)(3)], the Mo atom to ring-centroid distance in the η(6)-coordinated tricarbonyl-molybdenum group is 1.958 (1) Å. The three C O groups are pseudo-octa-hedrally disposed with C-Mo-C angles ranging from 80.7 (1) to 87.4 (1)°. The two uncoordinated 2,6-diisopropyl-phenyl-substituted benzene rings form dihedral angles of 75.96 (8) and 78.01 (9)° with the mean plane of the guanidine group. The coordinated benzene ring is in a slight sofa conformation with the N-substituted C atom and the bonded N atom dispaced by 0.090 (3) and 0.458 (4) Å, respectively, from the mean plane of the remaining ring atoms. In the crystal, despite there being two N-H donor groups, no conventional hydrogen bonds are present. This may be because of the steric effects of the bulky diisopropyl-phenyl groups.

In the title compound, (C(28)H(43)N(2))[SnCl(3)], two pairs of molecular species are present in the asymmetric unit. The employed α-diimine opens up, forming a highly asymmetric ammonium that has its protons at one of the N atoms [N-C= 1.264 (4) and 1.516 (4) Å]. One of the C=N double bonds was oxidized to C-N, which is consistent with the bond length of 1.516 (4) Å. Meanwhile Sn(IV) was reduce...

A new polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine, C(25)H(36)N(2), is reported, which is different from the previously reported ortho-rhom-bic structure. The mol-ecule crystallizes in the E-anti configuration, with tautomeric disorder of the N-bonded H atoms and no clear distinction between imine and amine functionalities. The mol-ecules form hydrogen-bonded dimers with inter-mol...

The title compound, C(13)H(19)NO, exhibits a non-planar structure in which the 2,6-diisopropyl-phenyl ring is tilted at a dihedral angle of 77.4 (1)° with respect to the formamide group. This is the largest dihedral angle known among structurally characterized formamides. The mol-ecules are linked via N-H⋯O hydrogen bonds, forming infinite chains which run along the b-axis directions.

In the title mol-ecule, C(30)H(42)N(6)O(2), the amide-substituted N atoms of the tetra-zine ring deviate from the approximate plane of the four other atoms in the ring by 0.457 (3) and 0.463 (3) Å, forming a boat conformation. The two benzene rings form a dihedral angle of 47.69 (9)°. Intra-molecular N-H⋯N and weak C-H⋯O hydrogen bonds are observed.
