Ornithophily

Pollination is a process where pollen grains are transferred from the stamens (male part) to the stigma (female part) of the flower; if it happens on the same plant it is called self pollination or if on another plant of the same species it is termed cross pollination. Pollination, however, is an accidental process that happens when animals such as bees, flies, wasps, moths, butterflies, bats, ants, beetles, and birds forage for food such as pollen and nectar from the flower. It also happens when the wind blows the pollen to the stigma of flowers. Wind pollinated flower are usually dull, small, without petals, and unscented. On the other hand, those flowers pollinated by animals are usually brightly-coloured and attractive, has a good amount of nectar or has a strong scent which can be sweet or foul smelling

High brain

Mitragyna speciosa or locally known as ketum in Malaysia is traditionally popular in the northern parts of Peninsular Malaysia and Thailand. The leaves are chewed or boiled and taken daily as a popular tonic by farmers to endure the sun, fatigue, and hard work. The truth is that ketum cheats the brain into believing that you are stronger than you thought

Crab signal system

In Peninsular Malaysia, mangrove crab fetches high commercial value and is a sought after seafood. This rare species contributes towards balancing the ecosystem through its daily activities such as burrowing and consuming leaf litter. Through burrowing, mangrove crab helps to aerate sediment through consuming leaf litter; and it also helps to retain much of the energy in the forest. The roles of this unique creature may be akin to an engineer of the forest

{S-Benzyl 3-[(6-methyl­pyridin-2-yl)­methyl­idene]dithio­carbazato}nickel(II) monohydrate

The structure of the title compound, [Ni(C15H14N3S2)2]·H2O, has one mol­ecule in the asymmetric unit, along with a solvent water mol­ecule. The two different Schiff base moieties coordinate to the central NiII ion as tridentate N,N′,S-chelating ligands, creating a six-coordinate distorted octa­hedral environment [the smallest angle being 77.43 (7)° and the widest angle being 169.99 (7)°]. The mean planes of the two ligands are nearly orthogonal to each other with an angle of 89.53 (6)°. The packing of the complex is supported by O—H⋯N and O—H⋯S hydrogen bonding between the solvent water mol­ecule and the uncoordinated N and S atoms of neighbouring ligands

Bis{S-benzyl 3-[(phen­yl)(pyridin-2-yl)methyl­idene]dithio­carbazato}zinc acetonitrile monosolvate

In the title compound, [Zn(C20H16N3S2)2]·CH3CN, two different Schiff base moieties coordinate to the central ZnII ion as tridentate N,N′,S-chelating ligands, creating a distorted octa­hedral environment [the smallest angle being 73.24 (6)° and the widest angle being 155.73 (7)°], with the two S atoms in cis positions. The dihedral angle between the mean planes of the two coordinating ligands is 83.65 (5)°. The crystal packing is consolidated by weak C—H⋯N hydrogen-bonding inter­actions

Crystal structure of (Z)-4-methylbenzyl 3-[1-(5-methylpyridin-2-yl)ethylidene]dithiocarbazate

In the title dithiocarbazate compound, C17H19N3S2, the central CN2S2 residue is essentially planar (r.m.s. deviation = 0.0288 Å) and forms dihedral angles of 9.77 (8) and 77.47 (7)° with the substituted-pyridyl and p-tolyl rings, respectively, indicating a highly twisted molecule; the dihedral angle between the rings is 85.56 (8)°. The configuration about the C=N bond is Z, which allows for the formation of an intramolecular N—H...N(pyridyl) hydrogen bond. The packing features tolyl-methyl-C—H...N(imine), pyridyl-C—H...π(tolyl) and π–π interactions [between pyridyl rings with a distance = 3.7946 (13) Å], which generates jagged supramolecular layers that stack along the b axis with no directional interactions between them

{S-Benzyl 3-[(6-methyl­pyridin-2-yl-κN)methyl­idene]dithio­carbazato-κ2 N 3,S}zinc

The title compound, [Zn(C15H14N3S2)2], contains two chemically equivalent Schiff base anions that are coordinated to the ZnII ion as tridentate N,N′,S-chelating ligands, creating a distorted octa­hedral environment [the smallest angle being 75.40 (6)° and the widest angle being 162.87 (6)°], with the two S atoms in cis positions. The dihedral angle between the mean planes of the two coordinating ligands is 85.65 (5)°. Weak C—H⋯S hydrogen bonds are also observed

Bis-(S-benzyl-β-N-(6-methylpyrid-2-yl)methylenedithiocarbazato) nickel(II).

The asymmetric unit of the title compound, [Ni(C15H 14N3S2)2], consists of two independent molecules with similar configurations. Each Ni2+ cation is coordinated in a cis-mode by two tridentate N,N′,S-chelating Schiff base ligands, creating a distorted octa-hedron [the smallest angle being 77.57 (7)° and the widest being 168.97 (7)° for one molecule, and 78.04 (7) and 167.55 (7)° for the second molecule]. The dihedral angle between the mean coordination planes of the two ligands is 86.76 (7)° for one and 89.99 (7)° for the second molecule. π-π inter-actions between neighbouring pyridine rings with plane-to-plane distances of 3.540 (1) and 3.704 (1) Å are observed
